[PATCH v2 20/40] scsi: leapraid: use 16-bits defined sense codes

From: Damien Le Moal <dlemoal@kernel.org>
Date: 2026-09-03 03:42:52
Also in: linux-s390, linux-scsi, linux-usb
Subsystem: leapio scsi raid driver, scsi subsystem, the rest · Maintainers: Dongdong Hao, "James E.J. Bottomley", "Martin K. Petersen", Linus Torvalds

Refactor the leapraid driver to use the 16-bits sense_code field of
struct scsi_sense_hdr and replace all hard-coded additional sense codes
and additional sense code qualifiers with the enum values defined in
include/scsi/scsi_sense.h. This helps with code clarity as the sense codes
being processed are easier to test and self-documented.

With this change, the locally defined macros for ASC and ASCQ values are
deleted.

No functional change intended.
