Subject: phy: qcom-qmp-ufs: drop unused in-layout configuration
X-Git-Tag: v6.6.17~5881^2~145
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=91496846a9e863f7caa2db4a828844746b6f6b32;p=platform%2Fkernel%2Flinux-rpi.git

phy: qcom-qmp-ufs: drop unused in-layout configuration

The QMP UFS PHY driver does not use the "in-layout" configuration macro
to configure registers that are typically accessed using "regs_layout"
arrays (e.g. QPHY_START_CTRL) so drop this unused feature.
