Subject: usb: phy: Find the right match in devm_usb_phy_match
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=869aee0f31429fa9d94d5aef539602b73ae0cf4b;p=openwrt%2Fstaging%2Fblogic.git

usb: phy: Find the right match in devm_usb_phy_match

The res parameter passed to devm_usb_phy_match() is the location where the
pointer to the usb_phy is stored, hence it needs to be dereferenced before
comparing to the match data in order to find the correct match.
