Subject: wanxl: fix info leak in ioctl
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.
