Which files to Patch in Kernel

[Rob]

I am working on writing a hint for enabling accessibility in LFS (
http://www.linuxfromscratch.org/
) As I recall it, something has to be commented out in serialio.c or serialio.h--I can't remember which one--in order to get hardware synths to work. Can someone please remind me which line has to be commented or changed?

Yes, the file is drivers/staging/speakup/serialio.c. You are looking for
the return statement after a line that issues a warning that says
"Unable to allocate port". When I build a patch, I change that warning
to say that it's continuing in spite of the error and I completely
remove the return statement. But the easiest thing to do is to just
comment out the return statement.
