Before setting HCI_INQUIRY bit check if HCI_OP_INQUIRY was really sent
otherwise the controller maybe be generating invalid events or, more
likely, it is a result of fuzzing tools attempting to test the right
behavior of the stack when unexpected events are generated.

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.

With subtle timings changes, we can now sometimes get an external abort on
non-linefetch error booting am3 devices at sysc_reset(). This is because
of a missing reset delay needed for the usb target module.

commit bce61476dc82f114e24e9c2e11fb064781ec563c upstream.
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.

commit 54cf39ec16335dadbe1ba008d8e5e98dae3e26f8 upstream.
The HTU21 offers 4 sampling frequencies: 20, 40, 70 and 120, which are
associated to an index that is used to select the right measurement
resolution and its corresponding measurement time. The current
implementation selects the measurement resolution and the temperature
measurement time properly, but it does not select the right humidity
measurement time in all cases.
In summary, the 40 and 70 humidity measurement times are swapped.
The reason for that is probably the unusual coding for the measurement
resolution. According to the datasheet, the bits [7,0] of the "user
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.
Fix lockdep false positive by setting a different class for parent and
children IRQ

This fixes a problem introduced while fixing ELD reporting with no jack
set.
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.

When an afs_volume struct is put, its refcount is reduced to 0 before

Unfortunately, this means that the lookup code can race and see a volume

because the refcount is 0, replace the node in the tree and set the

[ Upstream commit 39299bdd2546688d92ed9db4948f6219ca1b9542 ]
If a key has an expiration time, then when that time passes, the key is
left around for a certain amount of time before being collected (5 mins by
default) so that EKEYEXPIRED can be returned instead of ENOKEY. This is a
problem for DNS keys because we want to redo the DNS lookup immediately at
that point.
Fix this by allowing key types to be marked such that keys of that type
don't have this extra period, but are reclaimed as soon as they expire and
turn this on for dns_resolver-type keys. To make this easier to handle,
key->expiry is changed to be permanent if TIME64_MAX rather than 0.
Furthermore, give such new-style negative DNS results a 1s default expiry
if no other expiry time is set rather than allowing it to stick around
indefinitely. This shouldn't be zero as ls will follow a failing stat call
immediately with a second with AT_SYMLINK_NOFOLLOW added.

In the afs dynamic root directory, the ->lookup() function does a DNS check
on the cell being asked for and if the DNS upcall reports an error it will
report an error back to userspace (typically ENOENT).
However, if a failed DNS upcall returns a new-style result, it will return
a valid result, with the status field set appropriately to indicate the
type of failure - and in that case, dns_query() doesn't return an error and
we let stat() complete with no error - which can cause confusion in
userspace as subsequent calls that trigger d_automount then fail with
ENOENT.
Fix this by checking the status result from a valid dns_query() and
returning an error if it indicates a failure.
