Subject[PATCH 4.17 52/66] usb: xhci: Fix memory leak in xhci_endpoint_reset()
Date
4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Zheng Xiaowei <zhengxiaowei@ruijie.com.cn>

commit d89b7664f76047e7beca8f07e86f2ccfad085a28 upstream.

If td_list is not empty the cfg_cmd will not be freed,
call xhci_free_command to free it.
