Subject: [21/30] Input: pmouse - move Sentelic probe down the list
Date: Wed, 20 Jan 2010 20:15:42 -0800	[thread overview]
Message-ID: <20100121041835.206048238@mini.kroah.org> (raw)
In-Reply-To: <20100121041852.GA9656@kroah.com>

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Tai-hwa Liang <avatar@sentelic.com>

commit 4a18b3ab6ed537b055e3fcfca64ab870b4f9acf0 upstream.

Sentelic probes confuse IBM trackpoints so they stop responding to
TP_READ_ID command. See:

	http://bugzilla.kernel.org/show_bug.cgi?id=14970

Let's move FSP detection lower so it is probed after trackpoint and
others, just before we strat probing for Intellimouse Explorer.
