i2c: fix kernel memory disclosure in dev interface commit 30f939feaeee23e21391cfc7b484f012eb189c3c upstream. i2c_smbus_xfer() does not always fill an entire block, allowing kernel stack memory disclosure through the temp variable. Clear it before it's read to. Signed-off-by: Vlad Tsyrklevich <vlad@tsyrklevich.net> Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
