Bart Van Assche 6b9569a7a7 scsi: ufs: core: mcq: Fix ufshcd_mcq_sqe_search()
[ Upstream commit 3c5d0dce8c ]

Fix the calculation of the utrd pointer. This patch addresses the following
Coverity complaint:

CID 1538170: (#1 of 1): Extra sizeof expression (SIZEOF_MISMATCH)
suspicious_pointer_arithmetic: Adding sq_head_slot * 32UL /* sizeof (struct
utp_transfer_req_desc) */ to pointer hwq->sqe_base_addr of type struct
utp_transfer_req_desc * is suspicious because adding an integral value to
this pointer automatically scales that value by the size, 32 bytes, of the
pointed-to type, struct utp_transfer_req_desc. Most likely, the
multiplication by sizeof (struct utp_transfer_req_desc) in this expression
is extraneous and should be eliminated.
