Subject: [patch] watchdog: sch311x_wdt: fix printk condition
Date: Wed, 23 Feb 2011 20:26:01 +0000	[thread overview]
Message-ID: <20110223202601.GH19898@bicker> (raw)

"=" has higher precedence than "&".  Since
if (sch311x_sio_inb(sio_config_port, 0x30) & (0x01 = 0)) is always
false the message is never printed.

Btw, is this printk() even worth printing?
