Subject: drm/i915: cleanup: drm_modeset_lock_all_ctx() -->
DRM_MODESET_LOCK_ALL_BEGIN()
Git-commit: 399190e70816886e2bca1f3f3bc3d9c544af88e7
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
As requested in Documentation/gpu/todo.rst, replace the boilerplate code
surrounding drm_modeset_lock_all_ctx() with DRM_MODESET_LOCK_ALL_BEGIN()
and DRM_MODESET_LOCK_ALL_END()
