Subject: [patch] ASoC: wm8903: harmless underflow in wm8903_put_deemph()
Date: Tue, 13 Oct 2015 07:10:18 +0000 [thread overview]
Message-ID: <20151013071018.GF31537@mwanda> (raw)
Valid values for "deemph" are zero and one, but we accidentally allow
negative values as well. It's harmless, but static checkers complain
and we may as well clean it up.
