Hi Mark,

Will send a separate patch to fix this.

Anyhow, lets make sure that I got it right because looking into
sound/soc/codecs I can see a mixes of styles.

So, for ak5558.c the correct code should be:

// SPDX-License-Identifier: GPL-2.0
//
// Audio driver for AK5558 ADC
//
// Copyright (C) 2015 Asahi Kasei Microdevices Corporation
// Copyright 2018 NXP
//

Now, for the .h there is a total different story. As per Philippe's
link to documentation [1]

the .h file should start with:

C header:	/* SPDX-License-Identifier: <SPDX License Expression> */

So, is the header ak5558.h looking like this, all right?


/* SPDX-License-Identifier: GPL-2.0 */
/*
 * Audio driver header for AK5558
 *
 * Copyright (C) 2016 Asahi Kasei Microdevices Corporation
 * Copyright 2018 NXP
 */

Are you willing to take patches fixing the SPDX identifier for the rest of the codecs in sounc/soc/codecs?

I've got a bunch of students looking for cleanup patches in their application for Google Summer of Code :).

thanks,
Daniel.
