ASoC: rt1015: refactor retry loop and rt1015_priv allocation
Refactors retry loop in flush DAC work. It is more clear to use a for-loop here. Uses !rt1015 to check if NULL. Signed-off-by: Tzung-Bi Shih <tzungbi@google.com> Link: https://lore.kernel.org/r/20201224100607.3006171-5-tzungbi@google.com Signed-off-by: Mark Brown <broonie@kernel.org>
