[PATCH v5 0/2] media: qcom: iris: fix runtime PM error handling

[Hungyu Lin <dennylin0707@gmail.com>]

This series fixes two issues in the Iris power management path.

Patch 1 updates the runtime PM handling to use
pm_runtime_resume_and_get() and ensures that runtime PM references
remain balanced during power-down error handling.

Patch 2 rolls back the maximum OPP vote when
pm_runtime_resume_and_get() fails during power-up, preventing the
driver from leaving an unnecessary OPP vote active after a failed
resume.

Changes in v5:
- Handle pm_runtime_put_sync() return value in
  iris_disable_power_domains().
- Add a blank line before return statement in rollback path.

Changes in v4:
- Added Dmitry Baryshkov's Reviewed-by tag to patch 1.
- Reworked rollback handling in patch 2 to use a standard goto-based
  error path.
- Roll back the OPP vote from a dedicated error label when
  pm_runtime_resume_and_get() fails.
