Subject: [patch] [media] az6007: precedence bug in az6007_i2c_xfer()
Date: Wed, 25 Jan 2012 11:01:38 +0300 [thread overview]
Message-ID: <20120125080138.GB20199@elgon.mountain> (raw)
The intent here was to test that the flag was clear but the '!' has
higher precedence than the '&'. I2C_M_RD is 0x1 so the current code is
equivalent to "&& (!sgs[i].flags) ..."
