I beg to disagree with that statement...
sound/soc/codecs/wm9705.c: In function `wm9705_soc_suspend':
sound/soc/codecs/wm9705.c:326: error: `AC97_POWERDONW' undeclared (first use in this function)
sound/soc/codecs/wm9705.c:326: error: (Each undeclared identifier is reported only once
sound/soc/codecs/wm9705.c:326: error: for each function it appears in.)
sound/soc/codecs/wm9705.c: At top level:
sound/soc/codecs/wm9705.c:445: warning: initialization from incompatible pointer type
Fixing these results in something which can be built, and along with
your other two for the soc-core resume and the ac97 device parent,
the complaints from the touchscreen driver no longer appear.
Thanks.
