-Subject: [PATCH] staging: bcm2835-audio: Remove superfluous open flag
-
-commit ad13924de6b07cb52714ea1809c57b2e72a24504 upstream.
-
-All the alsa_stream->open flag checks in the current code are
-redundant, and they cannot be racy.  For the code simplification,
-let's remove the flag and its check.
