| Subject: staging: vt6655: Remove vif check from vnt_interrupt |
| |
| From: Malcolm Priestley <tvboxspy@gmail.com> |
| |
| 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. |
