If anyone has any objections, please let me know. ------------------ From: Axel Lin commit 869aee0f31429fa9d94d5aef539602b73ae0cf4b upstream. 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.
