Subject: [patch] pinctrl: abx500: fix bitwise AND test
Date: Mon, 26 Aug 2013 19:03:50 +0300 [thread overview]
Message-ID: <20130826160350.GE12428@elgon.mountain> (raw)
The intent here was to test if the bit was set or not but there is a
logical vs bitwise AND typo so it is true if any bits are set.
