usb: gadget: fusb300_udc: Fix memory leak of fusb300->ep[i]
There is no deallocation of fusb300->ep[i] elements, allocated at fusb300_probe. The patch adds deallocation of fusb300->ep array elements. Signed-off-by: Young Xiao <92siuyang@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
