I have some comments that I will mark inline below..... My comments are
just surface-level, as I havent messed around inside budget-av yet, so
others may have more to say...
BTW, your patch is whitepace-mangled.... after addressing the comments
from me (and any others) , please re-send your patch as a textfile
attachment.

^^^ Instead of doing this, can you please create a dvb_pll_desc so that
this tuner can be re-used by other modules? Then you can call it here
with something like:
dvb_pll_configure(&philips_sd1878_tda8261, buf, params->frequency, 0);

Everything else looks fine to me... Still, I would like someone else to
ACK this, since I dont know the budget-av module as well as others.
Please create that dvb_pll_desc .... It really helps for the future
development of any other devices that might use the same tuner. Of
course, you'll have to #include dvb-pll.h , etc.....
Cheers,
Michael Krufky
