+From 6e555781259281e31f8b5dc518a317511d67bbd8 Mon Sep 17 00:00:00 2001

+Subject: pcm: Return the consistent error code for unexpected PCM states
+
+Some PCM functions have the sanity check of the expected PCM states,
+and most of them return -EBADFD if the current state doesn't match.
+This is bad for some programs like aplay that expect the function
+returning a proper code corresponding to the state, e.g. -ESTRPIPE for
+the suspend.
+
+This patch is an attempt to address such inconsistencies. The sanity
+checker bad_pcm_state() now returns the error code instead of bool, so
+that the caller can pass the returned code as is. And it calls a new
+helper, pcm_state_to_error(), for obtaining the error code to certain
+known PCM error state.
+
+While we're at it, use the new pcm_state_to_error() for simplifying
+the existing code to retrieve the error code, too.
