Subject: [PATCH] usbip: Fix USB device hang due to wrong enabling of scatter-gather
Date: Thu, 30 Nov 2017 10:22:40 +0800 [thread overview]
Message-ID: <1512008560-28594-1-git-send-email-yuyang.du@intel.com> (raw)
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")
Reported-by: Juan Zea <juan.zea@qindel.com>
