3.8.13.16 -stable review patch. If anyone has any objections, please let me know. ------------------ From: =?UTF-8?q?Salva=20Peir=C3=B3?= <speiro@xxxxxxxxxx> [ Upstream commit 8e3fbf870481eb53b2d3a322d1fc395ad8b367ed ] The yam_ioctl() code fails to initialise the cmd field of the struct yamdrv_ioctl_cfg. Add an explicit memset(0) before filling the structure to avoid the 4-byte info leak. Signed-off-by: Salva Peiró <speiro@xxxxxxxxxx> Signed-off-by: David S.
