Merge patch series "scsi: ufs: Add support for the aggregated read query opcode"

Browse source 
Hyeoncheol Jeong <hyenc.jeong@samsung.com> says:

UFS 5.0 / JEDEC 220H introduces the AGGREGATED READ query opcode
(0x9), which retrieves an aggregated data packet bundling multiple
Descriptors, Attributes and Flags in a single QUERY RESPONSE
UPIU. Such a packet can be far larger than a single descriptor, so the
reserved (device management) tag gets a dedicated UCD with an enlarged
response area.

Patch 1 is a preparatory cleanup that switches the BSG query
descriptor length to unsigned types. Patch 2 adds the aggregated read
support.
