Hi Bart,

Yes, this patch can be applied independently, I was able to successfully
build it based on the following base-commit:
3ce97bd3c4f18608335e709c24d6a40e7036cab8.

However, please note that it may conflict with the following patch when
applied: https://lore.kernel.org/all/20260617143055.820096-1-wei.deng@oss.qualcomm.com/.

Best Regards
Sherry
