Hi Thomas,
powerpc and arm allmodconfig builds still fails with the same error.
Build logs of next-20161010 are at:
arm at https://travis-ci.org/sudipm-mukherjee/parport/jobs/166321467
powerpc at https://travis-ci.org/sudipm-mukherjee/parport/jobs/166321473

I know. This is under discussion with the driver folks as we are not going
to blindly export stuff just because someone slapped a irq_set_parent()
into the code w/o knowing why.

Do we have any idea if a resolution is close.  This was first reported
in linux-next in September 14/15.  :-(

Grr. Yes. As much as I hate it, I'll go and export it for now. Should be
able to get it into rc2.

kernel/irq: Export irq_set_parent()

The TPS65217 driver grew interrupt support which uses
irq_set_parent(). While it's not yet clear why this is used in the first
place, building the driver as a module fails with:

 ERROR: ".irq_set_parent" [drivers/mfd/tps65217.ko] undefined!

The correctness of the driver change is still investigated, but for now
it's less trouble to export irq_set_parent() than dealing with the build
wreckage.

[ tglx: Rewrote changelog and made the export GPL ]
