Subject: [patch] p54: clamp properly instead of just truncating
Date: Mon, 13 Jan 2014 22:05:23 +0300 [thread overview]
Message-ID: <20140113190523.GA9341@elgon.mountain> (raw)
The call to clamp_t() first truncates the variable signed 8 bit and as a
result, the actual clamp is a no-op.
Fixes: 0d78156eef1d ('p54: improve site survey')
