Hi!
There is a potential race in drivers/staging/speakup/speakup.ko.
All operations with global pointers buff_in and buff_out are performed
without any locks. Thus, a simultaneous write (via synth_buffer_clear or
synth_buffer_add) to the pointers may lead to inconsistent data.
Should a local lock be used here?
