[PATCH v2 0/2] media: ipu-bridge: survive module unload and reuse the software nodes on rebind

[D. Manresa]

Hello,

v2 of the ipu-bridge rebind series, addressing Sakari's review of v2/2:

- shortened the 2/2 commit message (dropped the cross-reference to 1/2
  and the IVSC/VCM elaboration);
- dev_info() -> dev_dbg() on the reuse path;
- replaced the free-text AI note with the Assisted-by: tag per
  Documentation/process/coding-assistants.rst, in both patches.

No code changes other than the log level. The v1 testing stands: on a
Surface Pro 7+ (IPU6, OV5693 + OV8865 + OV7251) the PCI remove ->
module unload -> rescan -> modprobe sequence, fatal today (-EEXIST),
completes cleanly with the series - twice in a row - with all three
cameras streaming after each rebind. (The same sequence with all sensor
sub-device drivers unbound first fails identically without the series,
as reported in the parent thread.)

Thanks,
D. Manresa
