[PATCH 4.4 64/79] staging: vt6655: Fix memory leak in vt6655_probe

[Greg Kroah-Hartman]

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

commit 80b15db5e1e9c3300de299b2d43d1aafb593e6ac upstream.

In vt6655_probe, if vnt_init() fails the cleanup code needs to be called
like other error handling cases. The call to device_free_info() is
added.

Fixes: 67013f2c0e58 ("staging: vt6655: mac80211 conversion add main mac80211 functions")
