From 53771a490e05e8be750a6ee50002e30df4776e9b Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 19 Jul 2017 21:49:59 +0800 Subject: [PATCH] usb: hub: Revise wLength for 'get port status' request For accuracy, we should use 'sizeof(struct usb_port_status)' as the wLength for 'get port status' request, although it happens to be equal to 'sizeof(struct usb_hub_status)'.
