From 68f831c2724ab72c0088471b2ed1dc99e81948ef Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 16 Jun 2014 18:13:05 +0200 Subject: [PATCH] ASoC: Add a set_bias_level() callback to the DAPM context struct Currently the DAPM code directly looks at the CODEC driver struct to get a handle to the set_bias_level() callback. This patch adds a new set_bias_level() callback to the DAPM context struct. The DAPM code will use this new callback instead of the CODEC callback. For CODECs the new callback is set up to call the CODEC specific set_bias_level callback(). Not looking directly at the CODEC driver struct will allow non CODEC DAPM contexts to implement a set_bias_level() callback. This is also similar to how the seq_notifier() and stream_event() callbacks are currently handled.
