2012-06-18video: tegra: dc: move set default videomode out of _tegra_dc_enable.tegra-15r7.1-android-4.0Marvin Zhang
Set default videomode happens during probe and resume. _tegra_dc_enable is also called during hotplug, setting default videomode there causes hdcp test failure. Also, fixes checkpatch.pl errors. bug 991805 Change-Id: Ica3cab9dd96d9766bd63301000ec29edc510ee34 Reviewed-on: http://git-master/r/109362 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Jon Mayo <jmayo@nvidia.com> Reviewed-by: Marvin Zhang <mzhang@nvidia.com> Tested-by: Marvin Zhang <mzhang@nvidia.com> Reviewed-by: Ryan Wong <ryanw@nvidia.com>
