Subject: [patch] TTY: snyclinkmp: calculating wrong addresses
Date: Fri, 19 Jul 2013 08:53:13 +0300 [thread overview]
Message-ID: <20130719055313.GF9729@elgon.mountain> (raw)
This is a static checker fix and I don't have a way to test it. But
from the context it looks like this is a typo where SCABUFSIZE was
intended instead of sizeof(SCABUFSIZE). SCABUFSIZE is 1024 and
sizeof(int) is 4. I would suspect this is a bad bug.
