From 1ac7cdc4b3b408c9f68475c4825176b9f04ee403 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 3 Apr 2015 08:13:14 -0300 Subject: [PATCH] [media] bttv: fix missing irq after reloading driver If pci_disable_device() isn't called when the driver is removed, then the next time when it is loaded the irq isn't found. I'm pretty sure this used to work in the past, but calling pci_disable_device() is clearly the correct method and this makes it work again.
