Subject: [media] cec: fix wrong last_la determination
From: Hans Verkuil <hverkuil@xs4all.nl>
[ Upstream commit f9f96fc10c09ca16e336854c08bc1563eed97985 ]
Due to an incorrect condition the last_la used for the initial attempt at
claiming a logical address could be wrong.
The last_la wasn't converted to a mask when ANDing with type2mask, so that
test was broken.
