Hi Markus,

Thank you for your thorough review of v3. This v5 addresses the issues
reported by the Media CI robot after v4 was submitted:
- Fixed build errors caused by incorrect struct member names
  (`immio` → `lmmio`, `pci_dev` → `pci`).
- Adjusted code alignment to satisfy checkpatch.pl (two CHECK
  warnings about open parenthesis alignment).

This v4 addresses all your comments:
- Added `Cc: stable@vger.kernel.org` to ensure the fix reaches stable
  kernels.
- Refactored the duplicate ioremap error handling into a helper function 
  to improve code clarity and reduce duplication.
- Replaced manual mutex lock/unlock with `scoped_guard()` 
  for better safety and readability.

Regarding the `Fixes` tag: I've added a tag pointing to the 
commit that originally introduced the driver. 
At that time, the file
was located at drivers/media/video/saa7164/saa7164-core.c; the `Fixes` tag
correctly identifies the commit where the issue first appeared, regardless
of the later file move.

The patch adds missing error checks for two ioremap calls in
saa7164_dev_setup(). If either mapping fails, the function now properly
releases previously allocated PCI resources, removes the device from the
global list, and returns -ENODEV. This prevents potential null pointer
dereferences and ensures proper cleanup on failure.

Please review the updated patch. Thanks!
