Merge tag 'drm-fixes-2024-05-11' of https://gitlab.freedesktop.org/drm/kernel
Pull drm fixes from Dave Airlie: "This should be the last set of fixes for 6.9, i915, xe and amdgpu are the bulk here, one of the previous nouveau fixes turned up an issue, so reverting it, otherwise one core and a couple of meson fixes. core: - fix connector debugging output i915: - Automate CCS Mode setting during engine resets - Fix audio time stamp programming for DP - Fix parsing backlight BDB data xe: - Fix use zero-length element array - Move more from system wq to ordered private wq - Do not ignore return for drmm_mutex_init amdgpu: - DCN 3.5 fix - MST DSC fixes - S0i3 fix - S4 fix - HDP MMIO mapping fix - Fix a regression in visible vram handling amdkfd: - Spatial partition fix meson: - dw-hdmi: power-up fixes - dw-hdmi: add badngap setting for g12 nouveau: - revert SG_DEBUG fix that has a side effect" * tag 'drm-fixes-2024-05-11' of https://gitlab.freedesktop.org/drm/kernel: Revert "drm/nouveau/firmware: Fix SG_DEBUG error with nvkm_firmware_ctor()" drm/amdgpu: Fix comparison in amdgpu_res_cpu_visible drm/amdkfd: don't allow mapping the MMIO HDP page with large pages drm/xe: Use ordered WQ for G2H handler drm/xe/guc: Check error code when initializing the CT mutex drm/xe/ads: Use flexible-array Revert "drm/amdkfd: Add partition id field to location_id" dm/amd/pm: Fix problems with reboot/shutdown for some SMU 13.0.4/13.0.11 users drm/amd/display: MST DSC check for older devices drm/amd/display: Fix idle optimization checks for multi-display and dual eDP drm/amd/display: Fix DSC-re-computing drm/amd/display: Enable urgent latency adjustments for DCN35 drm/connector: Add \n to message about demoting connector force-probes drm/i915/bios: Fix parsing backlight BDB data drm/i915/audio: Fix audio time stamp programming for DP drm/i915/gt: Automate CCS Mode setting during engine resets drm/meson: dw-hdmi: add bandgap setting for g12 drm/meson: dw-hdmi: power up phy on device init
