Merge patch series "scsi: ufs: core: Always read the descriptors with max length"
Arthur Simchaev <Arthur.Simchaev@wdc.com> says:
Read any descriptor with a maximum size of QUERY_DESC_MAX_SIZE.
According to the spec the device returns the actual size. Thus can
improve code readability and save CPU cycles. While at it, clean up
few leftovers around the descriptor size parameter.
