From e64834b5094ff4ef2cfd960b82f69c2c26345501 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 13 Feb 2025 15:43:42 +0100 Subject: [PATCH 2126/5403] drm/atomic-helper: Change parameter name of drm_atomic_helper_wait_for_vblanks() drm_atomic_helper_wait_for_vblanks() waits for vblank events on all the CRTCs affected by a commit. 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.
