Hmm.. I tried to apply it after -rc1. It didn't apply:

Is there any missing patches, or is it just due to some other changes from the

Ondrej,
Could you please rebase this patch on the top of staging/for_v3.0 branch at
git://linuxtv.org/media_tree.git tree?
The other patch applied ok (tea575x: convert to control framework), so I've
already applied it here.

Yeah, I didn't pick it up as the patches are rather V4L-side changes
(although tea575x.c is in sound sub-directory).
And I agree with Mauro - let's merge it after rc1, so that we stand on
the same ground. This sort of cross-tree change is better done at the
fixed point than in flux like during merge window.
That being said, I don't mind that Mauro or Hans applies these through
V4L tree. In that case, you can take my acks for both patches.
Acked-by: Takashi Iwai
Of if it's preferred through sound tree, I can take them later.

Ondrej,
As your first series went via alsa tree, and we are close to the end of the
merge window,
and assuming that Takashi didn't apply those patches on his tree, as you're
re-sending it,
I think that the better is to wait for the end of the merge window, in order to
allow us
to sync our development tree with 2.6.40-rc1, and then review and apply it on
the top of it.
Thanks,
Mauro.

[PATCH v5] [resend] radio-sf16fmr2: convert to generic TEA575x interface
Convert radio-sf16fmr2 to use generic TEA575x implementation. Most of the
driver code goes away as SF16-FMR2 is basically just a TEA5757 tuner
connected to ISA bus.
The card can optionally be equipped with PT2254A volume control (equivalent
of TC9154AP) - the volume setting is completely reworked (with balance control
added) and tested.
