Description Ralph Siemsen 2007-03-09 12:18:09 EST
Included program "inputattach.c" needs to be updated to a more recent version.

Longer Description:
The inputattach.c makes the call ioctl(SPIOCSTYPE) with argument SERIO_RS232
combined with other parameters.  This constant is defined in kernel header file,
but has changed value from 0x20000000 to 0x00000002 somewhat recently.  The new
value now conflicts with other parameters.  This results in inputattach being
unable to actually attach practically any external input device, because the
passed value will not match up with the tables in the kernel.

In the kernel the function serio_match_port() is where the problem is noticed. 
The comparison on the proto field always fails, because bits from the new value
of SERIO_RS232 interfere.
