Subject: [PATCH 3.10 18/65] usb: phy: Find the right match in devm_usb_phy_match

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Axel Lin <axel.lin@...ics.com>

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.

Fixes: 410219dcd2ba ("usb: otg: utils: devres: Add API's to associate a device with the phy")
