[PATCH 16/29] drm/atomic-helper: Change parameter name of drm_atomic_helper_fake_vblank()

From: Maxime Ripard
Date: Wed Jan 15 2025 - 16:08:47 EST


drm_atomic_helper_fake_vblank() fake a vblank event if needed when a new
commit is being applied. It takes the drm_atomic_state being committed
as a parameter.

However, that parameter name is called (and documented) as old_state,
which is pretty confusing. Let's rename that variable as state.
