Subject: [patch 1/1] rt2x00: fix "buffer size not provably correct" build warning
Date: Mon, 23 Aug 2010 00:37:11 +0200 [thread overview]
Message-ID: <20100822223718.431624390@rtp-net.org> (raw)
In-Reply-To: 20100822223710.865969746@rtp-net.org
rt2x00 debugfs interface doesn't check the size of the data coming
from userspace, leading to a build warning. Fix That.
