From a035c7e4107749687e7b2d1021d3d3fa067b3230 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 23 Jun 2011 12:40:58 -0300 Subject: [RHEL6 qemu-kvm PATCH 025/115] usb: move remote wakeup handling to common code RH-Author: Gerd Hoffmann Message-id: <1308832951-8995-23-git-send-email-kraxel@redhat.com> Patchwork-id: 27894 O-Subject: [RHEL-6.2 kvm PATCH 022/115] usb: move remote wakeup handling to common code Bugzilla: 561414 632299 645351 711354 RH-Acked-by: Hans de Goede RH-Acked-by: Jes Sorensen RH-Acked-by: Paolo Bonzini RH-Acked-by: Kevin Wolf This patch moves setting and clearing the remote_wakeup feature bit (via USB_REQ_{SET,CLEAR}_FEATURE) to common code. Also USB_REQ_GET_STATUS handling is moved to common code.
