[PATCH 19/80] drm/panfrost: Remove redundant pm_runtime_mark_last_busy() calls

From: Sakari Ailus
Date: Fri Jul 04 2025 - 03:59:44 EST


pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

In brief, this patch depends on PM runtime patches adding marking the last
busy timestamp in autosuspend related functions. The patches are here, on
rc2:
