commit b2fa9e13bbf101c662c4cd974608242a0db98cfc upstream.
The old rtl8188eu module, removed in commit 55dfa29b43d2 ("staging:
rtl8188eu: remove rtl8188eu driver from staging dir") (Linux kernel
v5.15-rc1), required (through a MODULE_FIRMWARE call()) the
rtlwifi/rtl8188eufw.bin firmware file, which the new r8188eu driver no
longer requires.
I have tested a few RTL8188EUS-based Wi-Fi cards and, while supported by
both drivers, they do not work when using the new one and the firmware
wasn't manually loaded. According to Larry Finger, the module
maintainer, all such cards need the firmware and the driver should
depend on it (see the linked mails).
Add a proper MODULE_FIRMWARE() call, like it was done in the old driver.
Thanks to Greg Kroah-Hartman and Larry Finger for quick responses to my
questions.

_Read/Write_MACREG callbacks are NULL so the read/write_macreg_hdl()
functions don't do anything except free the "pcmd" pointer. It
results in a use after free. Delete them.

[ Upstream commit 6a0c054930d554ad8f8044ef1fc856d9da391c81 ]
There are sleep in atomic context bugs when dm_fsync_timer_callback is
executing. The root cause is that the memory allocation functions with
GFP_KERNEL or GFP_NOIO parameters are called in dm_fsync_timer_callback
which is a timer handler. The call paths that could trigger bugs are
shown below:
(interrupt context)
dm_fsync_timer_callback
write_nic_byte
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
write_nic_dword
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
This patch uses delayed work to replace timer and moves the operations
that may sleep into the delayed work in order to mitigate bugs.

Not all DPB entries will be used most of the time. Unused entries will
thus have invalid timestamps. They will produce negative buffer index
which is not specifically handled. This works just by chance in current
code. It will even produce bogus pointer, but since it's not used, it
won't do any harm.
Let's fix that brittle design by skipping writing DPB entry altogether
if timestamp is invalid.

[ Upstream commit 9393761aec4c56b7f2f19d21f806d316731401c1 ]
When the post-processor hardware block is enabled, the driver
allocates an internal queue of buffers for the decoder enginer,
and uses the vb2 queue for the post-processor engine.
For instance, on a G1 core, the decoder engine produces NV12 buffers
and the post-processor engine can produce YUY2 buffers. The decoder
engine expects motion vectors to be appended to the NV12 buffers,
but this is only required for CODECs that need motion vectors,
such as H.264.
Fix the post-processor logic accordingly.

commit 09b204eb9de9fdf07d028c41c4331b5cfeb70dd7 upstream.
The three bugs are here:
__func__, s3a_buf->s3a_data->exp_id);
__func__, md_buf->metadata->exp_id);
__func__, dis_buf->dis_data->exp_id);
The list iterator 's3a_buf/md_buf/dis_buf' will point to a bogus
position containing HEAD if the list is empty or no element is found.
This case must be checked before any use of the iterator, otherwise
it will lead to a invalid memory access.
To fix this bug, add an check. Use a new variable '*_iter' as the
list iterator, while use the old variable '*_buf' as a dedicated
pointer to point to the found element.

In _rtw_init_xmit_priv, we use the res variable to store the error
return from the newly converted rtw_alloc_hwxmits function. Sadly, the
calling function interprets res using _SUCCESS and _FAIL still, meaning
we change the semantics of the variable, even in the success case.
This leads to the following on boot:
r8188eu 1-2:1.0: _rtw_init_xmit_priv failed
In the long term, we should reverse these semantics, but for now, this
fixes the driver. Also, inside rtw_alloc_hwxmits remove the if blocks,
as HWXMIT_ENTRY is always 4.

Besides, in r871xu_dev_remove(), r8712_usb_dvobj_deinit() will be called
by r871x_dev_unload() under condition `padapter->bup` and
r8712_free_io_queue() is called by r8712_free_drv_sw().
However, r8712_usb_dvobj_deinit() does not rely on `padapter->bup` and
calling r8712_free_io_queue() in r8712_free_drv_sw() is negative for

[ Upstream commit 309373a3571ef7175bd9da0c9b13476a718e8478 ]
The payload size for encoder capture buffers is set by the driver upon
finishing encoding each frame, based on the encoded length returned from
hardware, and whatever header and padding length used. Setting a
non-zero default serves no real purpose, and also causes issues if the
capture buffer is returned to userspace unused, confusing the
application.
Instead, always set the payload size to 0 for encoder capture buffers
when preparing them.

The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

- Remove gpio-leds node as the system LED is not wired to anywhere on
the board and the power LED is directly wired to GND.
- Remove uart3 pin group from gpio-pinmux node as it's not used as GPIO.
- Use reg 7 for the external phy to be on par with

- Use the status value "okay".

- Sort pin groups alphabetically.
Misc fixes:
- Fix formatting.
- Use the status value "okay".
- Define hexadecimal addresses in lower case.
- Make hexadecimal addresses for memory easier to read.
