scsi: ufs: sysfs: unit descriptor This patch introduces a sysfs group entry for the UFS unit descriptor parameters. The group adds "unit_descriptor" folder under the corresponding SCSI device sysfs entry (/sys/class/scsi_device/*/device/). The parameters are shown as hexadecimal numbers. The full information about the parameters could be found at UFS specifications 2.1.
