[linux-dvb] Re: [PATCH] skystar2 filters rewritten(?!)
Hi Niklas,
your patch looks fine to me, and IMHO should be added to cvs.
I'll attach a patch against cvs with a few changes:
- I corrected a wrong adapter variable name
- I added a few lines for enable_hw_filters=0
- I removed my name from the file, because I don't think I contributed much.
Many thanks for your nice work :-)
And of course many thanks to Vladim for his great work.
Wolfgang
