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.
