[PATCH linux dev-5.14] iio: aspeed_adc: Fix prescaler devres cleanup

[PATCH linux dev-5.14] iio: aspeed_adc: Fix prescaler devres cleanup

[Joel Stanley]

A devres hook is added for aspeed_adc_unregister_fixed_divider that
should pass a pointer to the fixed divider. It mistakenly had a pointer
to a different clock, leading to a null pointer dereference.

This change was included in v7 of the patches submitted upstream.

Fixes: ec35bd77c642 ("iio: adc: aspeed: Fix the calculate error of clock.")
