Re: [PATCH] Add support for PCTV452E.

Thanks for the review!

As this is the first time I touched module- / kernel-code and I am not really familiar with the structures of the rc-system, I do not really feel up to porting to non-legacy rc-support (Igors version also appears to use rc-legacy), and up to now, it was only combining patches and fixing small glitches for me. However, feel free to use me as a tester (I have the hardware available, after all) or flood me with links to guidelines or further instructions.

Thanks again,

Got it working with kernel 3.0!

For me, some more changes on the current patchset appeared to be necessary.
In short, I had to change all a->fe to a->fe[0] (because of 3.0-kernel)
and I had to add lnbp22 to Kconfig (it would otherwise have been
disabled and not been built, although other modules depended on it...).

I also had to add the additional
"EXPORT_SYMBOL(ttpci_eeprom_decode_mac);" as mentioned by Doychin Dokov.

Attached is the 'new' version of the patch with the mentioned changes.
For it to be applied, we need the SOB's of the patch authors:

+MODULE_AUTHOR("Dominik Kuhlen<dkuhlen@xxxxxxx>");
+MODULE_AUTHOR("Andre Weidemann<Andre.Weidemann@xxxxxx>");
+MODULE_AUTHOR("Michael H. Schimek<mschimek@xxxxxx>");

Also, the patch needs some adjustments to be applied. See bellow for my quick review:
