Hi Benjamin,

I love your patch! Yet something to improve:

[auto build test ERROR on media-tree/master]
[also build test ERROR on rockchip/for-next linus/master v6.2-rc3 next-20230112]
[cannot apply to pza/reset/next pza/imx-drm/next]
[If your patch is applied to the wrong git tree, kindly drop us a note.
