Subject: [patch] mmc: omap_hsmmc: precedence bug in omap_hsmmc_context_restore()
Date: Thu, 22 Aug 2013 15:56:13 +0300	[thread overview]
Message-ID: <20130822125613.GB2543@elgon.mountain> (raw)

'!' has higher precedence than '&' so this doesn't work as intended
although since RESETDONE is 1 it would work if none of the other bits
are set.

Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

Untested.
