Some custom ASoC kcontrol put() handlers use the written enum value
(ucontrol->value.enumerated.item[0]) to index a table or compute a bit
shift before validating that the value is within the control's enum range.
An out-of-range value written from userspace is therefore consumed before
it is rejected.
This is the same class addressed for the Meson codecs in commit
1e00120680 ("ASoC: meson: g12a-tohdmitx: Validate written enum values")
and commit 3150b70e94 ("ASoC: meson: g12a-toacodec: Validate written
enum values").
Fix four more instances:
- hdac_hdmi reads e->texts[item] before validation.
- aiu converts the item before validating it.
- fsl_audmix converts the item and uses the result before validation.
- tegra210_ahub reads e->values[item] before validation.
