| Subject: xhci: Fresco FL1100 controller should not have BROKEN_MSI quirk set. |
| |
| From: Mathias Nyman <mathias.nyman@linux.intel.com> |
| |
| commit e4844092581ceec22489b66c42edc88bc6079783 upstream. |
| |
| The Fresco Logic FL1100 controller needs the TRUST_TX_LENGTH quirk like |
| other Fresco controllers, but should not have the BROKEN_MSI quirks set. |
| |
| BROKEN_MSI quirk causes issues in detecting usb drives connected to docks |
| with this FL1100 controller. |
| The BROKEN_MSI flag was apparently accidentally set together with the |
| TRUST_TX_LENGTH quirk |
| |
| Original patch went to stable so this should go there as well. |
| |
| Fixes: ea0f69d82119 ("xhci: Enable trust tx length quirk for Fresco FL11 USB controller") |
