serial/bfin_5xx.c build error

Commit 7d01b475ab17018756c8df27c2ee3c220fab05f8
(Blackfin Serial Driver: Enable IR function when user application)
causes the following build error:

<--  snip  -->

In case it can't be fixed quickly a revert might be an option for 2.6.26.

Graf has already sent me a patch to fix this. After I test it on my
board, I will send it out for Linus git pull.

Thanks a lot

i dont think there's anything for us to do on our side.  i thought
Alan was sending the fix out for 2.6.26.

A revert wouldn't be an option as quick check would show you.

The needed enabler patch went into Linus tree so the other fix should
follow before 2.6.26 and all will be well.

Oh, no. Even with Alan and Linus pathc, we still need to fix some API change.
I will send it out soon.

So is this bug in mainline upstream or linux-next latest tree?

It was a bug in the mainline upstream kernel.

Alan fixed it with comit b1cbefe5d5fc2d4a6109961d914027172ce8e152 
(blackfin: Fix compile failure in tty code) that went into
Linus' tree last night.
