From 378a0ede126a2c59ab9ea1771de624521db5053e Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Wed, 18 Feb 2009 11:46:45 +0100 Subject: [PATCH] HID: fix USB HID devices after STD with autosuspend This patch fixes a bug caused by reset_resume not changing the internal status flags for a device that is resumed via reset_resume. To do so the reset handlers, which correctly assume that a device is awake, can no longer do all the work of reset_resume handling.
