[PATCH 4.4 112/131] staging: vt6655: Remove vif check from vnt_interrupt

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Malcolm Priestley <tvboxspy@xxxxxxxxx>

commit cc26358f89c3e493b54766b1ca56cfc6b14db78a upstream.

A check for vif is made in vnt_interrupt_work.

There is a small chance of leaving interrupt disabled while vif
is NULL and the work hasn't been scheduled.
