commit 23484d817082c3005252d8edfc8292c8a1006b5b upstream.
Fix the undefined usage of the GPIO consumer API after retrieving the
GPIO description with GPIO_ASIS. The API documentation mentions that
GPIO_ASIS won't set a GPIO direction and requires the user to set a
direction before using the GPIO.
This can be confirmed on i.MX6 hardware, where rfkill-gpio is no longer
able to enabled/disable a device, presumably because the GPIO controller
was never configured for the output direction.

commit ff49bf1867578f23a5ffdd38f927f6e1e16796c4 upstream.
If some of p9pdu_readf() calls inside case 'T' in p9pdu_vreadf() fails,
the error path is not handled properly. *wnames or members of *wnames
array may be left uninitialized and invalidly freed.
Initialize *wnames to NULL in beginning of case 'T'. Initialize the first
*wnames array element to NULL and nullify the failing *wnames element so
that the error path freeing loop stops on the first NULL element and
doesn't proceed further.

commit ea3715941a9b7d816a1e9096ac0577900af2a69e upstream.
This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.
While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

The reason is that although the device is detached, normal stop and
unbind operations are commanded from the driver. These operations are
not necessary in this situation, so avoid these logs when the device is
detached if the result of the operation is -ENODEV and if the new flag
informing about the disconnecting status is enabled.

commit 7fbcd195e2b8cc952e4aeaeb50867b798040314c upstream.
Here "temp" is the number of characters that we have written and "size"
is the size of the buffer. The intent was clearly to say that if we have
written to the end of the buffer then stop.
However, for that to work the comparison should have been done on the
original "size" value instead of the "size -= temp" value. Not only
will that not trigger when we want to, but there is a small chance that
it will trigger incorrectly before we want it to and we break from the
loop slightly earlier than intended.
This code was recently changed from using snprintf() to scnprintf(). With
snprintf() we likely would have continued looping and passed a negative
size parameter to snprintf(). This would have triggered an annoying
WARN(). Now that we have converted to scnprintf() "size" will never
drop below 1 and there is no real need for this test. We could change
the condition to "if (temp <= 1) goto done;" but just deleting the test
is cleanest.

commit 59b047bc98084f8af2c41483e4d68a5adf2fa7f7 upstream.
If two Bluetooth devices both support BR/EDR and BLE, and also
support Secure Connections, then they only need to pair once.
The LTK generated during the LE pairing process may be converted
into a BR/EDR link key for BR/EDR transport, and conversely, a
link key generated during the BR/EDR SSP pairing process can be
converted into an LTK for LE transport. Hence, the link type of
the link key and LTK is not fixed, they can be either an LE LINK
or an ACL LINK.
Currently, in the mgmt_new_irk/ltk/crsk/link_key functions, the
link type is fixed, which could lead to incorrect address types
being reported to the application layer. Therefore, it is necessary
to add link_type/addr_type to the smp_irk/ltk/crsk and link_key,
to ensure the generation of the correct address type.

commit 772685c14743ad565bb271041ad3c262298cd6fc upstream.
This flash drive reports write protect during the first mode sense.
In the past this was not an issue as the kernel called revalidate twice,
thus asking the device for its write protect status twice, with write
protect being disabled in the second mode sense.
However, since commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to
avoid calling revalidate twice") that is no longer the case, thus the
device shows up read only.
[490891.289495] sd 12:0:0:0: [sdl] Write Protect is on
[490891.289497] sd 12:0:0:0: [sdl] Mode Sense: 2b 00 80 08
This does not appear to be a timing issue, as enabling the usbcore quirk
USB_QUIRK_DELAY_INIT has no effect on write protect.

Commit ee708e6baacd ("iio: buffer: introduce support for attaching more
IIO buffers") introduced support for multiple buffers per indio_dev but
left indio_dev->buffer for a few legacy use cases.
In the case of the triggered buffer, iio_triggered_buffer_cleanup()
still assumes that indio_dev->buffer points to the buffer allocated by
iio_triggered_buffer_setup_ext(). However, since
iio_triggered_buffer_setup_ext() now calls iio_device_attach_buffer()
to attach the buffer, indio_dev->buffer will only point to the buffer
allocated by iio_device_attach_buffer() if it the first buffer attached.
This adds a check to make sure that no other buffer has been attached
yet to ensure that indio_dev->buffer will be assigned when
iio_device_attach_buffer() is called.
As per discussion in the review thread, we may want to deal with multiple
triggers per device, but this is a fix for the issue in the meantime and
any such support would be unlikely to be suitable for a backport.

commit 3b8157ec4573e304a29b7bced627e144dbc3dfdb upstream.
The current offset has the scale already applied to it. The ABI
documentation defines the offset parameter as "offset to be added
to <type>[Y]_raw prior to scaling by <type>[Y]_scale in order to
obtain value in the <type> units as specified in <type>[Y]_raw
documentation"
The right value is obtained at 0 degrees Celsius by the formula provided
in the datasheet:
T = Tsens_t0 + (Tadc_t - Tadc_t0) / Tadc_res
where:
T = 0 degrees Celsius
Tsens_t0 (reference temperature) = 25 degrees Celsius
Tadc_t0 (16-bit format for Tsens_t0) = 17508
Tadc_res = 60.1 LSB/degree Celsius
The resulting offset is 16005.5, which has been truncated to 16005 to
provide an integer value with a precision loss smaller than the 1-LSB
measurement precision.
Fix the offset to apply its value prior to scaling.

register" are used as follows to select the bit resolution:
--------------------------------------------------
| Bit 7 | Bit 0 | RH | Temp | Trh (us) | Tt (us) |
--------------------------------------------------
| 0 | 0 | 12 | 14 | 16000 | 50000 |
--------------------------------------------------
| 0 | 1 | 8 | 12 | 3000 | 13000 |
--------------------------------------------------
| 1 | 0 | 10 | 13 | 5000 | 25000 |
--------------------------------------------------
| 1 | 1 | 11 | 11 | 8000 | 7000 |
--------------------------------------------------
*This table is available in the official datasheet, page 13/21. I have
just appended the times provided in the humidity/temperature tables,
pages 3/21, 5/21. Note that always a pair of resolutions is selected.
The sampling frequencies [20, 40, 70, 120] are assigned to a linear
index [0..3] which is then coded as follows [1]:
Index [7,0]
--------------
idx 0 0,0
idx 1 1,0
idx 2 0,1
idx 3 1,1
That is done that way because the temperature measurements are being
used as the reference for the sampling frequency (the frequencies and
the temperature measurement times are correlated), so increasing the
index always reduces the temperature measurement time and its
resolution. Therefore, the temperature measurement time array is as
simple as [50000, 25000, 13000, 7000]
On the other hand, the humidity resolution cannot follow the same
pattern because of the way it is coded in the "user register", where
both resolutions are selected at the same time. The humidity measurement
time array is the following: [16000, 3000, 5000, 8000], which defines
the following assignments:
Index [7,0] Trh
-----------------------
idx 0 0,0 16000 -> right, [0,0] selects 12 bits (Trh = 16000)
idx 1 1,0 3000 -> wrong! [1,0] selects 10 bits (Trh = 5000)
idx 2 0,1 5000 -> wrong! [0,1] selects 8 bits (Trh = 3000)
idx 3 1,1 8000 -> right, [1,1] selects 11 bits (Trh = 8000)
The times have been ordered as if idx = 1 -> [0,1] and idx = 2 -> [1,0],
which is not the case for the reason explained above.
So a simple modification is required to obtain the right humidity
measurement time array, swapping the values in the positions 1 and 2.
The right table should be the following: [16000, 5000, 3000, 8000]
Fix the humidity measurement time array with the right idex/value
coding.
[1] The actual code that makes this coding and assigns it to the current
value of the "user register" is the following:
config_reg &= 0x7E;
config_reg |= ((i & 1) << 7) + ((i & 2) >> 1);

This warning is raised because pinctrl-at91-pio4 uses chained IRQ. Whenever
a wake up source configures an IRQ through irq_set_irq_wake, it will
lock the corresponding IRQ desc, and then call irq_set_irq_wake on "parent"
IRQ which will do the same on its own IRQ desc, but since those two locks
share the same class, lockdep reports this as an issue.

Most driver using the hdmi-codec will call the 'plugged_cb' callback
directly when registered to report the initial state of the HDMI connector.
With the commit mentionned, this occurs before jack is ready and the
initial report is lost for platforms actually providing a jack for HDMI.
Fix this by storing the hdmi connector status regardless of jack being set
or not and report the last status when jack gets set.
With this, the initial state is reported correctly even if it is
disconnected. This was not done initially and is also a fix.
