Re: media: ipu-bridge: lifetime of retained software-node properties

Hi Fernando, Dario,

I've incorporated v5 1/2 into the local flash integration.

With both v5 patches, QEMU tests passed 16 PCI remove/rescan cycles per
run, eight including bridge unload/reload, for both the original bridge
and our integration. Frequencies and lens references remained readable
while the bridge was unloaded. No KASAN or lockdep reports.

A synthetic X1 configuration also preserved the IR flash reference, LED
string property and limits through the same lifecycle tests.

Agreed on vcm_type: it is currently init-only, and I'd keep that cleanup
separate.

Could you confirm that capture works again on each previously working
sensor after module reload and repeated PCI remove/rescan with the full
v5 series? If you've already covered this, those results would be useful.

Regards,
Ruslan
