A client driver may use mhi_unprepare_from_transfer() to quiesce
incoming data during the client driver's tear down. The client driver
might also be processing data at the same time, resulting in a call to
mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
after mhi_unprepare_from_transfer() has torn down the channel, a panic
will occur due to an invalid dereference leading to a page fault.
This occurs because mhi_gen_tre() does not verify the channel state
after locking it. Fix this by having mhi_gen_tre() confirm the channel
state is valid, or return error to avoid accessing deinitialized data.

Hi All,
V3 of this patch adding headphone jack detection support to the Anbernic RGnnXX series of handhelds. V3 corrects my misunderstanding of derivation of ALSA UCM file paths, and adds recieved Reviewed-by and Tested-by tags. Thanks to those that have reviewed and fed back on previous versions.
Original message below:
This series adds the required device tree bindings to describe GPIOs for jack detection in the sun4i-codec driver, adds support for jack detection to the codec machine driver, and describes the hardware configuration in the RG35XX DTS. The existing speaker amplifier GPIO pin can then be used in concert with jack detection to enable userspace sound servers (via an ALSA UCM configuration) to disable the speaker route when headphones are connected.
Thanks to Chris Morgan for his assistance putting this series together.
Regards,
Ryan

Issue:
In the scenario where svm_range_restore_pages is called, but
svm->checkpoint_ts has not been set and the retry fault has not been
drained, svm_range_unmap_from_cpu is triggered and calls svm_range_free.
Meanwhile, svm_range_restore_pages continues execution and reaches
svm_range_from_addr. This results in a "failed to find prange..." error,
causing the page recovery to fail.
How to fix:
Move the timestamp check code under the protection of svm->lock.
v2:
Make sure all right locks are released before go out.
v3:
Directly goto out_unlock_svms, and return -EAGAIN.

On the off chance that command stream passed from userspace via
ioctl() call to radeon_vce_cs_parse() is weirdly crafted and
first command to execute is to encode (case 0x03000001), the function
in question will attempt to call radeon_vce_cs_reloc() with size
argument that has not been properly initialized. Specifically, 'size'
will point to 'tmp' variable before the latter had a chance to be
assigned any value.
Play it safe and init 'tmp' with 0, thus ensuring that
radeon_vce_cs_reloc() will catch an early error in cases like these.

Add remote processor PAS loaders for SM8750 MPSS (modem), which differs
from SM8650 by lack of fifth memory region for Qlink Logging.

Add remote processor PAS loader for SM8750 MPSS (modem). Device looks
fully compatible with SM8650, however it lacks fifth memory region for
Qlink Logging, according to downstream sources. This is a bit tricky,
because updated downstream sources for newer downstream release dropped
that fifth memory region as well.
There might be other differences against SM8650, because the modem
currently crashes after starting.

Adding jack detection requires sound servers to act on the emitted
events, which are described by ALSA Use Case Manager configurations in
userspace. These configurations include the long card name in the file
path (falling back to card->name if this is not present), so add a long
card name for the H616 without spaces, making UCM referencing easier.
The corresponding ALSA UCM patch is here (now merged):

Changelog v1..v2:
- Separate patch for card->long_name
- Note UCM patch link
Changelog v2..v3:
- Add card->long_name rather than change existing card->name

Add support for GPIO headphone detection with the hp-det-gpios
property. In order for this to properly disable the path upon
removal of headphones, the output must be labelled Headphone which
is a common sink in the driver.
Describe a headphone jack and detection GPIO in the driver, check for
a corresponding device tree node, and enable jack detection in a new
machine init function if described.

The previous H616 support patch added a single LINEOUT DAPM pin switch
to the card controls. As the codec in this SoC only has a single route,
this seemed reasonable at the time, however is redundant given the
existing DAPM codec widget definitions controlling the digital and
analog sides of the codec.
It is also insufficient to describe the scenario where separate
components (muxes, jack detection etc) are used to modify the audio
route external to the SoC. For example the Anbernic RG(##)XX series of
devices uses a headphone jack detection switch, GPIO-controlled speaker
amplifier and a passive external mux chip to route audio.
Remove the redundant LINEOUT card control, and add a Speaker pin switch
control and Headphone DAPM widget to allow control of the above
hardware.
