[PATCH] drivers/usb/input/ati_remote.c: autorepeat fix

From: Marko Macek
Date: Wed Jul 05 2006 - 00:32:26 EST


When HZ is set to 250 (new default) or 100, the time span during which repeated
events from the device are ignored could be too small due to ms->jiffies rounding. This causes the auto repeat to kick in early making it impossible for the user to generate individual press/release events. Increate the timeout to compensate.
