Subject: [PATCH 11/15] phy: qcom-ufs: Suppress extraneous logging

From: Bjorn Andersson <bjorn.andersson@...aro.org>

The error paths of the common qcom-ufs functions for registering the
phy, acquiring clocks and acquiring regulators all print specific error
messages before returning an error, so there is no value in printing yet
another - more generic - message when this occur.
