Laurent Pinchart eb2ed66fe5 drm/irq: Don't disable vblank interrupts when already disabled ... The .enable_vblank() operation is only called when vblank interrupts are disabled, but no similar check exists when disabling vblank interrupts. This leads to .disable_vblank() being called with vblank interrupts already disabled and the device possibly runtime suspended. As the operation is called with a spinlock held drivers can't runtime resume the device there and thus must avoid touching device registers in that case, requiring vblank refcounting. As the DRM core tracks whether vblank interrupts are enabled just skip the .disable_vblank() call when the interrupts are already disabled.
