Subject: [patch] Hostap: copying wrong data prism2_ioctl_giwaplist()
Date: Fri, 9 Aug 2013 12:52:31 +0300	[thread overview]
Message-ID: <20130809095231.GD29282@elgon.mountain> (raw)

We want the data stored in "addr" and "qual", but the extra ampersands
mean we are copying stack data instead.

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

Static checker stuff.  Untested.  Should probably be applied to -stable
as well.
