Subject: [PATCH] scsi: ufs: ufshpb: Clean up ufshpb_suspend()/resume()
Git-commit: 18ebe2390c6197738cbe67aa26acabe7815060bd
Patch-mainline: v5.19-rc1
References: jsc#PED-1183

ufshpb_resume() is only called when the HPB state is HPB_SUSPEND, so the
check statement for "ufshpb_get_state(hpb) != HPB_PRESENT" is useless.
