New randconfig build failure: rx51 asoc / gpiolib

[Russell King - ARM Linux]

Last night's omap randconfig found this.  This has only appeared in the
builds in the last few days, so it's a new regression for the changes
queued up for merge window:

sound/soc/omap/rx51.c:220:33: error: array type has incomplete element type
sound/soc/omap/rx51.c:222:3: error: field name not in record or union initializer
sound/soc/omap/rx51.c:222:3: error: (near initialization for 'rx51_av_jack_gpios')
sound/soc/omap/rx51.c:223:3: error: field name not in record or union initializer

which is caused by "struct snd_soc_jack_gpio" not being defined.  For
some reason, this structure is defined in sound/soc.h, but is
conditionalised upon CONFIG_GPIOLIB.

This means either the dependencies on SND_OMAP_SOC_RX51 are incorrect
(they don't include a dependency on GPIOLIB) or ASoC is wrong to make
the definitions conditional upon GPIOLIB.

in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
