scsi: ufs: fix static checker warning in ufshcd_populate_vreg
This patch fixes newly introduced static checker warning in ufshcd_populate_vreg, introduced by UFS power management series. Warning: drivers/scsi/ufs/ufshcd-pltfrm.c:167 ufshcd_populate_vreg() warn: missing error code here? 'devm_kzalloc()' failed. 'ret' = '0' To fix it we return -ENOMEM and skip the message print.
