How do you think about a wording variant like the following?

   Subject:
   [PATCH v2] net: rtw88: Complete exception handling in rtw_pci_io_mapping()

   Change description:
   A call of the function “pci_request_regions” can fail here.
   The corresponding system resources were not released then.
   Thus add a call of the function “pci_release_regions”.
