3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Salva Peiró <speiro@xxxxxxxxxx> [ Upstream commit 2b13d06c9584b4eb773f1e80bbaedab9a1c344e1 ] The wanxl_ioctl() code fails to initialize the two padding bytes of struct sync_serial_settings after the ->loopback member. Add an explicit memset(0) before filling the structure to avoid the info leak. Signed-off-by: Salva Peiró <speiro@xxxxxxxxxx> Signed-off-by: David S.
