Subject: drm: omapdrm: Simplify DSS power management
X-Git-Tag: omap-for-v4.2/fixes-rc1^2~17^2~16^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=69fb7c855c7bd4b4bc3fd6bec0885236365d5261;p=pandora-kernel.git

drm: omapdrm: Simplify DSS power management

Instead of sprinkling dispc_runtime_get() and dispc_runtime_put() calls
in various CRTC operations, move all power management code to the atomic
commit function.
