β¨ NAME β¨
ipc_pm_wait_for_device_active β literally just sits there and waits up to IPC_PM_ACTIVE_TIMEOUT_MS ms for the device to reach active state. that's it. that's the whole job. no cap. π
πΈ SYNOPSIS πΈ
bool ipc_pm_wait_for_device_active (struct iosm_pm *ipc_pm );
like, you hand her a pointer and she gives you back a bool. short. sweet. iconic. π
