Hello Adrian,
Sorry for late reply.
The code that returns true when CONFIG_SCSI_UFS_DWC is set in the original code
is only changed using the IS_ENABLED macro.
(Linux kernel coding style, 21) Conditional Compilation)
When CONFIG_SCSI_UFS_DWC is not defined, the code for checking quirk
and caps has been moved to the newly added return statement below.
Thanks,
Keoseong
