[PATCH 0/1][SRU][Jammy] UBSAN warnings in Intel IPU6 camera driver at boot

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1958006

[Impact]

Several UBSAN warnings captured on Intel IPU6 camera equipped platforms
running 5.15+ kernels.

[Fix]

Upstream fix commit 8dcb7d8df28f ("media: pci: intel: Avoid UBSAN
warnings of index bound and shift").

[Test Case]

Boot Intel IPU6 camera equipped platforms and check dmesg.

[Where problems could occur]

This patch turns a few return statements to error to stop further
processing that may fall in UBSAN warnings. No other side effect.

[Other Info]

While plan for -generic and oem-5.17 is still under discuss, only Jammy
is nominated for linux-oem-5.14/focal migration (to hwe-5.15).

This depends on the pull request titled "Support Intel IPU6 MIPI camera
on Alder Lake platforms" for bug 1955383 for Jammy.
