[PATCH v5 0/4] E5010 Probe Cleanup and Adding autosuspend

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.

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
