52ea796b91 phy: qcom-ufs: Don't return error if fail to get optional resource 
"dev_ref_clk_ctrl_mem" is optional resource, so don't return error if fail to
get the resource. Since it's an optional resource, don't emit error if
fail to get dev_ref_clk_ctrl_mem.

Also remove redundant test for res, it's done by devm_ioremap_resource().

d89a7f69d6 phy: qcom-ufs: Catch devm_phy_create failure in ufs_qcom_phy_generic_probe 
Current code does NULL test against return value of ufs_qcom_phy_generic_probe.
However, in the case of devm_phy_create() failure, ufs_qcom_phy_generic_probe
does not return NULL. Fix it.

adaafaa393 phy: qcom-ufs: add support for QUALCOMM Technologies UFS PHY drivers 
This change adds a generic and common API support for ufs phy QUALCOMM
Technologies. This support provides common code and also points
to specific phy callbacks to differentiate between different behaviors
of frequent use-cases (like power on, power off, phy calibration etc).
