X-Git-Tag: v4.19.224~8 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a3d19b025a4d21705570b54ba4478baa9fd8cd8b;p=users%2Fdwmw2%2Flinux.git xhci: Fresco FL1100 controller should not have BROKEN_MSI quirk set. 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.
