From cc26358f89c3e493b54766b1ca56cfc6b14db78a Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Wed, 27 Mar 2019 18:45:26 +0000 Subject: [PATCH] staging: vt6655: Remove vif check from vnt_interrupt 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.
