Subject: drm: omapdrm: inline omap_plane_setup into update/disable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11ffd031e3e5b9cc0232aad549bb08eb14612f43;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm: omapdrm: inline omap_plane_setup into update/disable

At the moment we have omap_plane_setup() function which handles both
enabling (and configuring) and disabling the plane. With atomic
modesetting we have separate hooks for plane enable/config and disable.

This patch moves the code from omap_plane_setup() to
omap_plane_atomic_update() and omap_plane_atomic_disable().
