From 3128f1c3b53d73e35e1069663736284358fcdd01 Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih Date: Thu, 24 Dec 2020 18:06:06 +0800 Subject: 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.
