Merge tag 'drm-next-2022-03-25' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Some fixes were queued up in and in light of the fbdev regressions, I've pulled those in as well. core: - Make audio and color plane support checking only happen when a CEA extension block is found. - Small selftest fix. fbdev: - two regressions fixes from speedup patches. ttm: - Fix a small regression from ttm_resource_fini() i915: - Reject unsupported TMDS rates on ICL+ - Treat SAGV block time 0 as SAGV disabled - Fix PSF GV point mask when SAGV is not possible - Fix renamed INTEL_INFO->media.arch/ver field" * tag 'drm-next-2022-03-25' of git://anongit.freedesktop.org/drm/drm: fbdev: Fix cfb_imageblit() for arbitrary image widths fbdev: Fix sys_imageblit() for arbitrary image widths drm/edid: fix CEA extension byte #3 parsing drm/edid: check basic audio support on CEA extension block drm/i915: Fix renamed struct field drm/i915: Fix PSF GV point mask when SAGV is not possible drm/i915: Treat SAGV block time 0 as SAGV disabled drm/i915: Reject unsupported TMDS rates on ICL+ drm/selftest: plane_helper: Put test structures in static storage drm/ttm: Fix a kernel oops due to an invalid read
