[PATCH 3.13.y-ckt 41/48] ASoC: fix broken pxa SoC support

From: Kamal Mostafa
Date: Tue Oct 27 2015 - 17:36:13 EST

3.13.11-ckt29 -stable review patch. If anyone has any objections, please let me know.


From: Robert Jarzmik <robert.jarzmik@xxxxxxx>

commit 3c8f7710c1c44fb650bc29b6ef78ed8b60cfaa28 upstream.

The previous fix of pxa library support, which was introduced to fix the
library dependency, broke the previous SoC behavior, where a machine
code binding pxa2xx-ac97 with a coded relied on :
- sound/soc/pxa/pxa2xx-ac97.c
- sound/soc/codecs/XXX.c

For example, the mioa701_wm9713.c machine code is currently broken. The
"select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
pxa2xx-ac97 compilation.
