-Subject: [PATCH] Fix for Pisound kernel module in Real Time kernel
- configuration.
-
-When handler of data_available interrupt is fired, queue_work ends up
-getting called and it can block on a spin lock which is not allowed in
-interrupt context. The fix was to run the handler from a thread context
-instead.
