usb: gadget: zero: Fix SuperSpeed enumeration for alternate setting 1 It was impossible to enumerate on a SuperSpeed (XHCI) host with alternate setting = 1 due to the wrongly set 'bMaxBurst' field in the SuperSpeed Endpoint Companion descriptor. Testcase: <host> modprobe -r usbtest; modprobe usbtest alt=1 <device> modprobe g_zero plug device to SuperSpeed port on the host. Without this patch the host always complains like so "usb 12-2: Not enough bandwidth for new device state. usb 12-2: Not enough bandwidth for altsetting 1" Bug was introduced by commit cf9a08ae in v3.9 Fixes: cf9a08ae5aec (usb: gadget: convert source sink and loopback to new function interface) Cc: 3.9+ <stable@vger.kernel.org> # 3.9+ Reviewed-by: Felipe Balbi <balbi@ti.com> Acked-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
