| Subject: USB: Add LPM quirk for Surface Dock GigE adapter |
| |
| From: Maximilian Luz <luzmaximilian@gmail.com> |
| |
| commit ea261113385ac0a71c2838185f39e8452d54b152 upstream. |
| |
| Without USB_QUIRK_NO_LPM ethernet will not work and rtl8152 will |
| complain with |
| |
| r8152 <device...>: Stop submitting intr, status -71 |
| |
| Adding the quirk resolves this. As the dock is externally powered, this |
| should not have any drawbacks. |
