Commit d0db84e ASoC: omap-mcbsp: Fix 6pin mux configuration

changed a line within omap_mcbsp_6pin_src_mux() function to fix an error which
prevents the mux configuration in 3.4, 3.5, 3.6 kernels.

Commit 8fef626 ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration code

should remove this function fir 3.7 and the mux configuration should be done
in the board files or via DTS.

You have reported when you applied the McBSP DT series that commit 8fef626 had
conflict when you applied it. This was because I have created the series on on
a branch where the 6pin function was already fixed since I knew it is going to
be in 3.6 when the 3.7 merge will open.

So how can we resolve this?
Are you going to rebase or update your 3.7, for-next topic/omap branches on
mainline so they will contain the mainline patch (d0db84e)?
Not sure if I mentioned it but I have created a branch (for you to take, or
observe):
git://gitorious.org/omap-audio/linux-audio.git peter/topic/for-mark/omap-3.7

Here I have your topic/omap branch rebased on mainline and I have fixed the
commit 8fef626 and added the missing chunk in order to avoid build failure.

A patch against your 3.7, for-next, topic/omap will not apply in linux-next
and a patch on top of linux-next would not apply in the asoc tree.

Please let me know how can I help to resolve this - I do not want 3.7-rc1 to
be broken when it comes out for OMAP audio.

Thank you,
Péter
