Subject: irda: do not leak initialized list.dev to userspace

From: Colin Ian King <[email protected]>

[ Upstream commit b024d949a3c24255a7ef1a470420eb478949aa4c ]

list.dev has not been initialized and so the copy_to_user is copying data from the stack back to user space which is a potential information leak. Fix this ensuring all of list is initialized to zero.
