Subject: [PATCH v2 0/2] scsi: ufs: convert probe to use dev_err_probe()

The following two log messages are shown on bootup due to an
-EPROBE_DEFER when booting on a Qualcomm sa8775p development board:

ufshcd-qcom 1d84000.ufs: ufshcd_variant_hba_init: variant qcom init
failed err -517
ufshcd-qcom 1d84000.ufs: Initialization failed

This patch series converts the relevant two probe functions over to use
dev_err_probe() so that these messages are not shown on bootup.

Convert ufshcd_pltfrm_init() over to use dev_err_probe() to avoid
the following log message on bootup due to an -EPROBE_DEFER return
code:

ufshcd-qcom 1d84000.ufs: Initialization failed

Hi Brian,
Can you pls add the error code to the print?
