[PATCH 02/26] ASoC: SOF: reset default d0_substate at probe() and resume()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Keyon Jie <yang.jie@xxxxxxxxxxxxxxx>

We initialize/reset d0_substate to default d0i0 value when doing
transition D3-->D0, e.g. at success of probing and resuming.
