Ville Syrjälä bb9ca240dc drm/i915: Lock gmbus/aux mutexes while changing cdclk ... gmbus/aux may be clocked by cdclk, thus we should make sure no transfers are ongoing while the cdclk frequency is being changed. We do that by simply grabbing all the gmbus/aux mutexes. No one else should be holding any more than one of those at a time so the lock ordering here shouldn't matter. v2: Use mutex_lock_nest_lock() (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200302174442.5803-1-ville.syrjala@linux.intel.com Acked-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>		2020-03-09 22:28:33 +02:00
