Any objection to get it merged?

Sudeep Holla noticed that there is merge conflict against linux-next
with PIC32 uart (Makefile and serial_core.h), so should I provide
conflict resolution or do rebase on someone's branch?

Anyway, I'd be glad to know how it should be processed further?

Thanks
Vladimir

This patchset should go through the arm-soc tree. Any conflicts resulting
from a merge *after* your patchset is in the arm-soc tree is no longer your
problem.

So IOW, if your patchset applies to arm-soc and Arnd is ok to pick it, then
everything is fine.

I have no objection to the tty/serial changes, so if this all goes
through the arm-soc tree, that's fine with me.

Thanks Greg, can I take this as Ack ? arm-soc guys might expect to see
that tag :)

Hi Vladimir,

I have pulled this series into
git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git 
for-next/armv7-vexpress-updates

I will stick Greg's tag when it comes.
