| Subject: usbip: Fix USB device hang due to wrong enabling of scatter-gather |
| |
| From: Yuyang Du <yuyang.du@intel.com> |
| |
| commit 770b2edece42fa55bbe7d4cbe53347a07b8968d4 upstream. |
| |
| The previous USB3 SuperSpeed enabling patches mistakenly enabled |
| URB scatter-gather chaining, which is actually not supported by |
| the VHCI HCD. This patch fixes that. |
| |
| Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=197867 |
| Fixes: 03cd00d538a6feb ("usbip: vhci-hcd: Set the vhci structure up to work") |
