X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cfc67f0740cede2a6aec94b8513285d00c46d5f;p=openwrt%2Fstaging%2Fblogic.git

usb: otg: OMAP4430: Fixing the omap4430_phy_init function

omap4430_phy_init() function can be called with no device pointer,
to powerdown the PHY during board init when USB is disabled.
Fix the function accordingly.
