We have a number of "uart.port->desc.lock vs desc.lock->uart.port"
lockdep reports coming from 8250 driver; this causes a bit of trouble
to people, so let's fix it.

I guess we may add some tags here

Fixes: 768aec0b5bcc ("serial: 8250: fix shared interrupts issues with SMP and RT kernels")

"Link:" tag should point to the mail that is applied using git am.
I am not sure if there is a tag for related discussion in another
mail threads.

It's fine to have several Link tags and in the past we have them for bug
reports thru mailing lists or so.

Andy proposed many changes. Sergey, could you please send v2?

There is a v2.
