Subject: [PATCH] scsi: csiostor: Switch to attribute groups
Git-commit: 623cf762c73e300849d4dad94d9fdb749b5e2072
Patch-mainline: v5.16-rc1
References: jsc#PED-1561

struct device supports attribute groups directly but does not support
struct device_attribute directly. Hence switch to attribute groups.
