[PATCH v2 14/14] ASoC: sunxi: simplify optional reset handling

[PATCH v2 14/14] ASoC: sunxi: simplify optional reset handling

[Philipp Zabel]

As of commit bb475230b8e5 ("reset: make optional functions really
optional"), the reset framework API calls use NULL pointers to describe
optional, non-present reset controls.

This allows to return errors from devm_reset_control_get_optional and to
call reset_control_deassert unconditionally.
