Revision 6e20fb18054c179d7e64c0af43d855b9310a3394 authored by Roland Stigge on 10 February 2011, 23:01:23 UTC, committed by Linus Torvalds on 12 February 2011, 00:12:20 UTC
Add a mutex to register communication and handling. Without the mutex, GPIOs didn't switch as expected when toggled in a fast sequence of status changes of multiple outputs.
