Subject: [PATCH v1] drm/modes: Don't apply cmdline's rotation if it wasn't specified

The rotation mode from cmdline shouldn't be taken into account if it
wasn't specified in the cmdline. This fixes ignored default display
orientation when display mode is given using cmdline without the
rotation being specified.

Fixes: 1bf4e09227c3 ("drm/modes: Allow to specify rotation and reflection on the commandline")

Thank you. Please note that I'm not a DRM maintainer, hence either you
should pick up and apply the patch by yourself or somebody else who has
the commit rights will have do that. I guess Thierry could also pick up
the patch into the Tegra's tree, but this patch is more DRM-generic.
