[alsa-devel] Driver for TerraTec DMX 6Fire USB

[Torsten Schenk]

Hello,

Thanks very much for the review. I corrected the issues you wrote about (except the last one, see below). checkpatch.pl reports now 0 errors and warnings.

Another thing about the driver's features:
I'm currently in contact with a guy that also owns a TT DMX6FireUSB. He says, firmware is not loading for him. I'm trying to figure out how to make
it work, but I already know, that my driver cannot provide fw uploading for every device out there by now. I think it's just a matter of removing some checks, but I want to make as sure as I can before I just do so.

If the device was previously used in windows and not unplugged from power, it will work also with no firmware upload.

I though so. checkpatch.pl is a useful script, good to know it exists.

How is it supposed to be? I reviewed my code and added a prefix to every function. Hopefully
it didn't get too long now... Some, especially functions with not much content, seem to have a too long name by now for my flavour. 

>NULLs are automatically filled, so these can be skipped. 
Which NULLs are automatically filled? Just the area create by snd_card_create or
every area allocated via kmalloc? If last is true, I will have to remove some more NULLs.

Didn't know these exists...
When I used C once, 'bool' and also 'min'/'max' weren't available.

Just forgot ;)

Thanks, just copied this from another definition without exactly knowing what it does...

Realized that after posting.

I'd love not to ;) But how can I remove it? It's automatically generated by diff. Perhaps wrong arguments? Mine are -Nur
Or should I simply remove these lines with a text editor?

Greetings,
Torsten
