fb2ee9bf08 drm: panel-lvds: Potential Oops in probe error handling 
The "lvds->backlight" pointer could be NULL in situations where
of_parse_phandle() returns NULL.  This code is cleaner if we use the
managed devm_of_find_backlight() so the clean up is automatic.

455d56ce80 drm/v3d: clean caches at the end of render jobs on request from user space 
Extends the user space ioctl for CL submissions so it can include a request
to flush the cache once the CL execution has completed. Fixes memory
write violation messages reported by the kernel in workloads involving
shader memory writes (SSBOs, shader images, scratch, etc) which sometimes
also lead to GPU resets during Piglit and CTS workloads.

v2: if v3d_job_init() fails we need to kfree() the job instead of
    v3d_job_put() it (Eric Anholt).

v3 (Eric Anholt):
  - Drop _FLAG suffix from the new flag name.
  - Add a new param so userspace can tell whether cache flushing is
    implemented in the kernel.

8c8ae2fe8d drm/encoder: Fix possible_clones documentation 
We say that all of the bits in possible_clones must be set before
calling drm_encoder_init(). This isn't true though, since:

* The driver may not even have all of the encoder objects that could be

* possible_crtcs isn't used at all outside of userspace, so it's not
  actually needed to initialize it until drm_dev_register()

2f932367d2 drm/bridge: analogix-anx78xx: convert to i2c_new_dummy_device 
The i2c_new_dummy() function is deprecated since it returns NULL on
error. Change this to use the recommended replacement
i2c_new_dummy_device() that returns an error code that can be read with
PTR_ERR() and friends.

3250cdf938 drm: bridge/dw_hdmi: add audio sample channel status setting 
When transmitting IEC60985 linear PCM audio, we configure the
Aduio Sample Channel Status information in the IEC60958 frame.
The status bit is already available in iec.status of hdmi_codec_params.

This fix the issue that audio does not come out on some monitors
(e.g. LG 22CV241)

Note that these registers are only for interfaces:
I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA
(AHBAUDDMA).
For S/PDIF interface this information comes from the stream.

Currently this function dw_hdmi_set_channel_status is only called
from dw-hdmi-i2s-audio in I2S setup.

This patch only moves code without functional changes.
