[PATCH] drm/atomic: Don't reject reflect-only rotations

[Gustavo Padovan]

Hi Brian,

2016-12-07 Brian Starkey <brian.starkey at arm.com>:

> The check to reject combinations of multiple rotation angles is overly
> restrictive and has the side-effect of also failing any rotation value
> which consists only of reflections.
> 
> Fix this by relaxing the check to ignore values which contain no
> rotation flags.
> 
> Fixes: 6e0c7c3358d4 ("drm/atomic: Reject attempts to use multiple rotation angles at once")
