Subject: V4L/DVB: cx231xx: card->driver "Conexant cx231xx Audio" too long
X-Git-Tag: v2.6.35-rc1~480^2~309
X-Git-Url: https://bbs.cooldavid.org/git/?a=commitdiff_plain;h=935539c97ed5f4f46867e7f44e42ad2048403f4e;p=net-next-2.6.git

V4L/DVB: cx231xx: card->driver "Conexant cx231xx Audio" too long

card->driver is 15 characters and a NULL, the original code could
cause a buffer overflow.
