Subject: drm/sti: Store correct CRTC index in events
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=df00d029d7f107aa4b35edffca0465664e7289bd;p=linux-beck.git

drm/sti: Store correct CRTC index in events

A negative pipe causes a special case to be triggered for drivers that
don't have proper VBLANK support. STi does support VBLANKs, so there is
no need for the fallback code.
