From 700ab5e27925f883888501e9e2630ad8b8da49f7 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Tue, 8 Sep 2026 18:02:41 +0900 Subject: [PATCH] scsi: device_handlers: hp_sw: Use combined sense codes Refactor the HP sw device handler driver to use the 16-bit sense_code field of struct scsi_sense_hdr and struct scsi_failure 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. No functional change intended.
