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

------------------

From: Dawid Wróbel <[email protected]>

commit 56f24311fd5607588a47e44675195a9efb200f29 upstream.

EAR SPKR PA Gain" and the four "WSA RX* Mux" controls are enumerated,
but their get and put callbacks access the 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 with CONFIG_SND_CTL_DEBUG this trips the elem value
sanity check and every read of these controls fails with -EINVAL.

Fixes: 809bcbcecebf ("ASoC: codecs: lpass-wsa-macro: Add support to WSA Macro")
Fixes: 2c4066e5d428 ("ASoC: codecs: lpass-wsa-macro: add dapm widgets and route")
