From 5daf53a6eb5c54c618c9def388d81c2769fd11a0 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 19 May 2012 07:57:03 -0300 Subject: [media] snd_tea575x: Make the module using snd_tea575x the fops owner Before this patch the owner field of the /dev/radio# device fops was set to the snd-tea575x-tuner module itself. Meaning that the module which was using it could be rmmod-ed while the device is open, and then BAD things happen. I know, as I found out the hard way :) Note that there is no need to also somehow increase the refcount of the snd-tea575x-tuner module itself, since any drivers using it will have symbolic references to it.
