This warning comes from drivers/media/pci/intel/ivsc/mei_csi.c line 681 and
it is related to IVSC (Intel Vision Sensing Controller) present on some
systems with IPU6. The driver is necessary for the camera to work in these
systems but then again not all the necessary drivers were in place before
6.10 so this can't be said to be a regression.
The warning is made less verbose by commit
cc864821c7e8b921ebbfb21b17c92f8b3ea3d7ff (on Linus's tree).
