Subject: [PATCH] staging: vt6655: Remove vif check from vnt_interrupt
Git-commit: cc26358f89c3e493b54766b1ca56cfc6b14db78a
Patch-mainline: v5.1-rc3
References: bsc#1051510
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.
