From fb76b099f86624d3c629cfab071aa2296f65b7bb Mon Sep 17 00:00:00 2001 From: Vojtech Pavlik Date: Mon, 5 Sep 2005 00:12:39 -0500 Subject: Input: iforce - use wait_event_interruptible_timeout The timeout while() loops in iforce-packets.c lack a set_current_state(TASK_INTERRUPTIBLE); call. The right solution is to replace them with wait_event_interruptible_timeout().
