[PATCH 0/4] tty/serial: at91: fixes dealing with port shutdown

[Nicolas Ferre]

Hi,

These four fixes are pretty important for our atmel_serial driver as they
deal with closing/re-opening of ports. They fix race condition and
null pointers dereference.
I added the "stable" tag to each of them (v3.12).

Even if we are late in the development cycle, can you please consider including
these patches for 3.13?

Thanks, best regards,
   Nicolas Ferre
