Subject: [PATCH 4.2.y-ckt 48/98] ASoC: wm_adsp: Fix enum ctl accesses in a wrong type

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Takashi Iwai <tiwai@...e.de>

commit 15c665700bf6f4543f003ac0fbb1e9ec692e93f2 upstream.

The firmware ctls like "DSP1 Firmware" in wm_adsp codec driver are
enum, while the current driver accesses wrongly via
value.integer.value[].  They have to be via value.enumerated.item[]
instead.
