small char/generic_serial.c cleanup
PATCH 1/1 small char/generic_serial.c cleanup
The patch below does the following changes to drivers/char/generic_serial.c :
- make two needlessly global functions static
- remove the completely unused EXPORT_SYMBOL'ed function gs_do_softint
AFAIR the latter should be safe, since drivers are moving away from generic_serial.c .
