fails on the hotplug slot which doesn't have _STA method. If the

I think your patch has a bad effect to this kind of slots. So I
think your patch needs additional checks to see if the slot should
be enabled or not.

This patch fixes the problem that uninitialized (NULL) 'info' member
of uart_port structure can be accessed if serial driver is accessed
through /proc filesystem before uart_open(), which initializes the
'info' member', is called.

(). This
is why we fix this problem in 8250 driver. But if there is a
possibility that other drivers accesses port-info in their
-get_mctrl(), we should be fixing this in uart_read_proc(), as
you said.
How about the following patch? We've also confirmed the problem
is fixed by it.
