From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> The CHV CGM CSC registers are single buffered and so we may have to write them from the vblank worker, which imposes very tight dealines. Drop the pointless locking for the register accessess to reduce the overhead. All the other registers we bash from the vblank worker (LUTs) were already made lockless earlier.
