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
