Greybus Codec driver allows modules to be dynamically added and removed, which further requires updating the DAPM configurations as well. With current snd_soc architecture, dynamic audio modules is not yet supported. This patch provides helper APIs to update DAPM configurations in response to modules which are dynamically added or removed. The source is primarily based on snd_dapm.c Signed-off-by: Vaibhav Agarwal <vaibhav.sr@gmail.com> Reviewed-by: Dan Carpenter <dan.carpenter@oracle.com> Link: https://lore.kernel.org/r/35e1baaae10a3f2162e71be4c2f75a701584f0e6.1594290158.git.vaibhav.sr@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
