[PATCH 2/2] ASoC: codecs: lpass-wsa-macro: Fix enum kcontrol accesses

[Dawid Wróbel via B4 Relay]

From: Dawid Wróbel <me@xxxxxxxxxxxxxxx>

The "EAR SPKR PA Gain" control is enumerated, but
wsa_macro_ear_spkr_pa_gain_get() and _put() access its value
through ucontrol->value.integer.value[0] (a long) instead of
ucontrol->value.enumerated.item[0] (an unsigned int).

This same pattern was fixed in the sibling drivers by
commit bcfe5f76cc40 ("ASoC: codecs: rx-macro: fix accessing array
out of bounds for enum type") and
commit 0ea5eff7c606 ("ASoC: codecs: va-macro: fix accessing array
out of bounds for enum type"), but wsa-macro was missed.

On 64-bit kernels built with CONFIG_SND_CTL_DEBUG, the elem value
sanity check catches the 4 bytes written past the enumerated item
and every read of this control fails with -EINVAL (access overflow).

Fixes: 809bcbcecebf ("ASoC: codecs: lpass-wsa-macro: Add support to WSA Macro")
