drm/radeon/kms: clean up multiple crtc handling for evergreen+ (v2)
evergreen+ asics have 2-6 crtcs. Don't access crtc registers for crtc regs that don't exist as they have very high latency and may cause problems on some asics. The previous code missed a few cases and was not fine grained enough (missed the 4 crtc case for example). Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=38800 v2: fix typo noticed by Chris Bandy <cbandy@jbandy.com> Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Reviewed-by: Michel Dänzer <michel@daenzer.net> Tested-by: Simon Farnsworth <simon.farnsworth@onelan.co.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>
