commit f8313ef1f448006207f12c107123522c8bc00f15 Author: Jiri Kosina <jkos...@suse.cz> Date: Sat Jan 8 01:37:26 2011 -0800 Input: i8042 - introduce 'notimeout' blacklist for Dell Vostro V13 i8042 controller present in Dell Vostro V13 errorneously signals spurious timeouts. Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts and apply this quirk automatically for Dell Vostro V13, based on DMI match. In addition to that, this machine also needs to be added to nomux blacklist.
