Vaibhav Agarwal 3994e0b139 greybus: audio: use variable 'is_connected' to maintain module state ... there is race condition between _disconnect() request & stop_trigger() in case of abrupt module removal. And sometimes this can lead to deadlock while acquiring codec_info->lock. To avoid such situation, atomic variable is used to maintain codec connected state. During dai operations (trigger, shutdown, etc.), 'is_connected' variable is validated to avoid unnecessary lock acquire in case module already removed.
