Subject: drm: omapdrm: Pass integer source coordinates to omap_plane_mode_set()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a350da8be4d91e733ec8cb225e5edefa8b085167;p=linux-beck.git

drm: omapdrm: Pass integer source coordinates to omap_plane_mode_set()

The function will convert the Q16 source coordinates to integers, avoid
converting integers to Q16 first and perform the opposite conversion.
