[PATCH for v4.9 LTS 051/111] [media] cec: fix wrong last_la determination

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hans Verkuil <hverkuil@xxxxxxxxx>

[ 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.
