usbip: Fix USB device hang due to wrong enabling of scatter-gather
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> Signed-off-by: Yuyang Du <yuyang.du@intel.com> Cc: stable <stable@vger.kernel.org> Acked-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
