From 399d31da4e2f701ba91cdb4b39e074d6e16174a9 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Mon, 15 Sep 2008 17:29:28 +0200 Subject: [PATCH] USB: RESET_RESUME needs to block autosuspend when remote wakeup is needed Reset upon resumption will wipe the input buffer and is therefore a reason to not suspend if remote wakeup is requested because the driver needs that data.
