Re: [alsa-devel] [PATCH 2/4] soundwire: add enumeration_complete structure

On 23-10-19, 16:06, Pierre-Louis Bossart wrote:

We need an async mechanism to prevent access to Slaves that are not fully-enumerated.

init_completion() will be invoked when the Slave becomes UNATTACHED, and complete() will be invoked when the state become ATTACHED. Any read/write before this status change will be delayed with a wait_for_completion().
