dmasound module on PowerBook

From: Geert Uytterhoeven <geert@linux-m68k.org>

In arch/ppc/kernel/feature.c, we have

    #ifdef CONFIG_PMAC_PBOOK
    #ifdef CONFIG_DMASOUND_MODULE
	    /* On PowerBooks, we disable the sound chip when dmasound is a module
	     * */
	    if (controller_count && find_devices("via-pmu") != NULL) {
		    feature_clear(controllers[0].device, FEATURE_Sound_power);
		    feature_clear(controllers[0].device, FEATURE_Sound_CLK_enable);
	    }
    #endif
    #endif

Shouldn't the sound chip be disabled if dmasound is not compiled at all, i.e.
#if defined(CONFIG_PMAC_PBOOK) && !defined(CONFIG_DMASOUND)?

Gr{oetje,eeting}s,

On  26 Mar, this message from Geert Uytterhoeven echoed through cyberspace:

Shouldn't the sound chip be disabled if dmasound is not compiled at all, i.e.
#if defined(CONFIG_PMAC_PBOOK) && !defined(CONFIG_DMASOUND)?
or rather

#if defined(CONFIG_PMAC_PBOOK) && !(defined(CONFIG_DMASOUND_AMIGA)||defined(CONFIG_DMASOUND_.. others))

since CONFIG_DMASOUND is gone...

And anyhow, CONFIG_DMASOUND_MODULE needs to be replaced with something
else, since it seems to be gone as well?

Why the others? They don't matter for PowerBook anyway.

The *_MODULE defines are derived from the * defines. Hence it's
CONFIG_DMASOUND_AWACS_MODULE now.

It need to be disabled when it's not compiled at all or when it's in a
module (the module knows how to power it back up when insmod'ed). So yes,
this code won't handle the case where it's not compiled at all and needs
fixing.
