| Subject: usb: phy: Find the right match in devm_usb_phy_match |
| |
| From: Axel Lin <axel.lin@ingics.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") |
