Repost about fm801 tea575x_tuner in 2.6 kernels

[Kovalyev Sergey]

Hello all!

When I trying to do

#modprobe snd_fm801 tea575x_tuner=1

I see this thing in my syslog:

kernel: videodev: "TEA5757 radio" has no release callback. Please fix 
your driver for proper sysfs
support, see http://lwn.net/Articles/36850/

As far as I understand, this module is not compatible with linux-2.6 
kernels, so, how to fix this problem?


WBR, RandoMan.

Nope. This message is only warning and completely harmless. The driver
should work. This patch will remove the warning:

Hm...
Under 2.4.x kernels I used this command:
modprobe snd_fm801 tea575x_tuner=2
Now, under 2.6, it says that "2" is invalid valut into syslog:
kernel: snd_fm801: `2' invalid for parameter `tea575x_tuner'
So, I trying to use
modprobe snd_fm801 tea575x_tuner=1.
Seems that all ok, even fm says that all ok,
but I hear nothing. Master and Aux channels are unmuted and set to 
maximum value...
(This situation is under 2.6.8.1 with built-in alsa drivers)

The radio chip cannot be detected. Here is the patch which will fix
the module parameter (and use tea575x_tuner=2 as for 2.4):

Big big thanks! Radio works now!
