Merge remote branch 'intel/drm-intel-fixes' of /ssd/git/drm-next into drm-fixes
* 'intel/drm-intel-fixes' of /ssd/git/drm-next: drm/i915/sdvo: Always add a 30ms delay to make SDVO TV detection reliable MAINTAINERS: INTEL DRM DRIVERS list (intel-gfx) is subscribers-only drm/i915/sdvo: Always fallback to querying the shared DDC line drm/i915: Handle pagefaults in execbuffer user relocations drm/i915/sdvo: Only enable HDMI encodings only if the commandset is supported drm/i915: Only save/restore cursor regs if !KMS drm/i915: Prevent integer overflow when validating the execbuffer
