Subject: [PATCH] scsi: megaraid_sas: Switch to attribute groups
Git-commit: 09723bb252caaf5384439319ff599acbd93ddc2f
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.
