[libcamera-devel] [PATCH 0/6] libcamera: control serializer fixes

[Jacopo Mondi]

This series has started from investigating an error triggered by running
consecutive capture sessions with the IPU3 IPA module running in isolation.

>From there a few more fixes/improvements have lead me to be capable to running
CTS with isolated IPA with a single failure (the flaky recording tests).

Patch 1 is a small cleanup of the IPU3 IPA interface.
Patches 2, 3 and 4 fix issues in the control serializer, most of them went not
noticed as the IPA is seldom run isolated for the moment.

Patch 5 is a small drive-by change

Patch 6 fixes a log standing debt, and add the ability to ser/deser the
ControlInfo::def field.

Thanks
