[PATCH v1 6/7] drm/bridge: Drop drm_bridge_chain_mode_fixup
From: Sam Ravnborg <hidden>
Date: 2021-07-22 06:26:38
Also in:
dri-devel, linux-arm-kernel
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for bridge chips, the rest · Maintainers:
David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Andrzej Hajda, Neil Armstrong, Robert Foss, Linus Torvalds
There are no users left and we do not want to have this function available. drm_atomic_bridge_check() is used to call the mode_fixup() operation for the chained bridges and there is no need for drm_atomic_bridge_check(). Drop it.
