Subject: drm/omap: convert dss_mgr_ops to use omap_channel
X-Git-Tag: next-20160307~69^2^2~25
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e5cbb6e8eaa6d4ae8b4acafd59e2e058105c8177;p=karo-tx-linux.git

drm/omap: convert dss_mgr_ops to use omap_channel

We are removing the use of 'struct omap_overlay_manager' from omapdrm.
This patch changes the function pointers in 'dss_mgr_ops' to get 'enum
omap_channel' parameter instead of 'struct omap_overlay_manager'.

The change is very straightforward, as we still use 'struct
omap_overlay_manager' inside the function implementations where needed.
