Subject: drm: omapdrm: Store the rotation property in dev->mode_config
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e2cd09b202c5d32804f72bc28a9ed5a7d8a34452;p=linux-beck.git

drm: omapdrm: Store the rotation property in dev->mode_config

Rotation is a standard property, store it in
dev->mode_config.rotation_property. While at it, extract the properties
initialization code to a separate function instead of running it for
every plane.
