The following patch causes the serial driver for the GTA0x devices to print an
error message in the event of a UART error. The primary intent of this change
is to assist in field problem determination by ensuring that the presence or
absence of UART buffer overflows can be easily determined by a simple "dmesg"
command.
This patch is _not_ suitable for upstream.
