3.2.53-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Salva Peiró <spe...@ai2.upv.es>
[ Upstream commit 96b340406724d87e4621284ebac5e059d67b2194 ]
The fst_get_iface() 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.
