Subject: [patch] [media] mxl111sf: fix a couple precedence bugs
Date: Thu, 29 Sep 2011 09:09:42 +0300 [thread overview]
Message-ID: <20110929060942.GA4104@elgon.mountain> (raw)
Negate has higher precedence than bitwise AND. I2C_M_RD is 0x1 so
the original code is equivelent to just checking if (!msg->flags).
