scsi: ufs: mcq: Fix missing argument 'hba' in MCQ_OPR_OFFSET_n
Browse files Browse the repository at this point in the history
The MCQ_OPR_OFFSET_n macro takes 'hba' in the caller context without
receiving 'hba' instance as an argument.  To prevent potential bugs in
future use cases, add an argument 'hba'.

Fixes: 2468da6 ("scsi: ufs: core: mcq: Configure operation and runtime interface")
