[PATCH v8 0/4] E5010 Probe Cleanup and Adding autosuspend

[Brandon Brnich <b-brnich@ti.com>]

Hello all,

I noticed a report from the intel bot[0] which pointed out a valid issue
with the driver never calling e5010_init_device unless CONFIG_PM was
enabled. 

While looking at probe though, I noticed that the clk_enable was never
properly called. That has now been fixed with a proper remove path as
well.

Lastly, I cleaned up the goto jumps in probe to fix an issue where the
m2m_dev wasn't being freed.

The rest of the series is setting up the driver for properly adding in
support for autosuspend. Last patch adds in autosuspend support and
moves e5010_init_device into probe for cases where PM isn't enabled.

Changes since v7:

- patch 3 subject wasn't formatted correctly after I updated it so
  wasn't properly showing up

Changes since v6:

- Patch 2 changed order of calls during remove cleanup. video unregister
  now happens before pm disable
- patch 3 was updated to account for the case where a reset was called
  and the device was never properly reinitialized
- patch 3 has moved setting the last_run_context to NULL as well to
  always update QP values when device is turned back on/reinitialized
- removed the r-b by Kendall, Devarsh, and Jai since I have made a
  slight code change requested by Devarsh
- patch 4 remove the last_run_context in runtime resume hook that it had
  before because I moved it to patch 3
- patch 4 has updates to commit message to accurately reflect why
  init_device was added to probe
- patch 4 has updates where disable autosuspend now comes before disable
  pm

Changes since v5:

- Fix patch 1 not properly removing all references to the
  fail_after_video_register_device label

Changes since v4:

- Change authorship of patch 1 since Myeonghun sent a similar patch
  first
- addressed Devarsh's comments in Patch 1 to follow similar naming
  structure as rest of probe function
- Moved the clk_enable call after pm_runtime_enable here so I can check
  success of that call. If runtime pm is enabled then don't enable the
  clock here
- Patch 3 no changes
- Patch 4 I added the macro requested by Devarsh instead of using magic
  number
- failure to power on now goes through the existing no_ready_buf_err path,
  so buffers are marked as error and the job is finished

Changes since v3:

  - patches 1 and 2 are new in v4
  - patch 3 remains unchanged
  - patch 4:
      - updated goto to match changes in patch 1
      - update PM calls in probe

Best,
Brandon
