Hi all,
I gave a try to 2.6.15-rc7 and "make menuconfig" tells me:
Warning! Found recursive dependency: VIDEO_SAA7134_ALSA VIDEO_SAA7134_OSS VIDEO_SAA7134_ALSA
This seems to be the consequence of this patch:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7bb9529602f8bb41a92275825b808a42ed33e5be
How do we fix that? menuconfig is indeed really confused by the current
setup. I have the following patch which makes it happier:

Philips SAA713x based TV cards using OSS
However, I am not entirely happy with it because it introduces an
asymmetry: the OSS variant can no more be built-in, it is now only
available as a module. Not sure this is acceptable.
Another possibility would be to fix Kconfig to properly support this
case. Roman, what do you think?
Yet another possibility would be to not express the dependencies,
explain the mutual exclusion in the help texts, and hope that the user
will read the help texts. I doubt this will work. This seems to be what
was done for the eepro100/e100 case though (well, not even help texts
in this case).
Are there other similar cases in the kernel right now?
It would be nice to fix this before 2.6.15.
Thanks,
