 I gather this is to fix a potential inconsistency with the size of the 
buffer allocated by the serial core (though in reality this driver will 
only be used with 4KiB-page systems), right?  If so, then please state it 
in the change description.

 Also I'd rather:

#define DZ_WAKEUP_CHARS      UART_XMIT_SIZE

and there's no need to include <linux/serial_core.h> in dz.h as the driver 
itself already does that (and dz.h is an auxiliary private header).

 Thanks for your submission.
