I cherry-picked the two patches from linux-next:

  e1a875703470 ("pmdomain: imx-gpcv2: Suppress bind attrs")
  afb2a86f002b ("pmdomain: imx8m[p]-blk-ctrl: Suppress bind attrs")

but I still have the same warnings:

[    5.427038] Device 'mediablk-mipi-csi2-1' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst.
[    6.464219] Device 'mediablk-mipi-dsi-1' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst.

[    7.303529] Device 'mediablk-mipi-dsi-1' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst.

[    8.598453] Device 'mediablk-mipi-dsi-1' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst.

This is with 6.13-rc3 on a imx8mp.
