JFYI.

git am command could not work correctly by this lib.py file:
---
Applying: dt-bindings: PCI: dwc: Add interrupts/interrupt-names common properties
error: lib.py: does not exist in index
Patch failed at 0001 dt-bindings: PCI: dwc: Add interrupts/interrupt-names common properties
---

If I used patch command and skipped the lib.py, it could apply this patch correctly.

Best regards,
