[PATCH 0/3] pmdomain: imx: Use pm_runtime_resume_and_get()

[phucduc.bui]

From: bui duc phuc <phucduc.bui@gmail.com>

Hi all,

This series replaces open-coded pm_runtime_get_sync() and
pm_runtime_put_noidle() error handling with
pm_runtime_resume_and_get() in the i.MX power domain drivers.

No functional change.

Found by manual code inspection.

Best regards,
Phuc

[PATCH 1/3] pmdomain: imx: gpcv2: Use pm_runtime_resume_and_get()

[phucduc.bui]

From: bui duc phuc <phucduc.bui@gmail.com>

Replace the open-coded pm_runtime_get_sync() + pm_runtime_put_noidle()
error handling pattern with pm_runtime_resume_and_get(), which already
does this internally.

No functional change.
