patch for serial synths

[John Heim]

    Here is a link to a patch file that I believe will fix the bug that 
causes modprobe to error out when you try to load a speakup module for a 
serial synth.

To apply the patch:

1. Download the patch file at 
http://www.math.wisc.edu/~jheim/downloads/patch-2012-03-06.patch.
2. cd to the directory where you uncompressed the linux source code.
3. Apply the patch with the patch command. For example, if you saved the 
patch file  to /tmp/patch-2012-03-06.patch, you would type:

patch linux/drivers/staging/speakup/serialio.c -i 
/tmp/patch-2012-03-06.patch

4. Build your kernel as usual.
