IPU6 Camera doesn't work after a resume from hibernation (but does after a suspend)

(This seems to actually be an LJCA/GPIO issue; if I should move this elsewhere please let me know).

After coming out of hibernation (i.e., full power to my XPS-9320 was cut) my camera won't work:

I'm not at all familiar with all the plumbing used to get the IPU cameras to work, but I believe the LJCA USB adaptor is used as a GPIO expander to control the camera. It looks to me that perhaps the .resume hook has to take into account resumption from power loss.

This happens with both my kernel (Linus' master as of today, 6.19-rc2) and the latest Kubuntu stock kernel (6.17.0-8-generic).

LMK if you need further information. I have dmesg from both kernels' boots if it helps.
