From 4d96799524159f7c3e774a7b45a308780a26dc4d Mon Sep 17 00:00:00 2001 From: Xenia Ragiadakou Date: Sat, 31 Aug 2013 18:09:13 +0300 Subject: usbcore: fix incorrect type in assignment in usb_set_lpm_parameters() In the bos usb_ss_cap_descriptor structure, bU2DevExitLat is of type __le16. This value is used as it is, without being first converted to the CPU byteorder, for the setup of usb device's usb3_lpm_parameters. This patch fixes that by converting bU2DevExitLat field to the CPU byteorder before the assignmenment to [udev/hub]_u2_del variables.
