Subject: drm/tegra: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN()
X-Git-Tag: v6.6.17~3937^2~23^2~3771
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a2cd9947d99b54c959fce20dc19d81af53f4674e;p=platform%2Fkernel%2Flinux-rpi.git

drm/tegra: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN()

As requested in Documentation/gpu/todo.rst, replace driver calls to
drm_modeset_lock_all() with DRM_MODESET_LOCK_ALL_BEGIN() and
DRM_MODESET_LOCK_ALL_END()
