From 74ff960222d90999508b4ba0d3449f796695b6d5 Mon Sep 17 00:00:00 2001 From: Pascal Huerst Date: Thu, 2 Apr 2015 10:17:40 +0200 Subject: [PATCH] ASoC: cs4271: Increase delay time after reset The delay time after a reset in the codec probe callback was too short, and did not work on certain hw because the codec needs more time to power on. This increases the delay time from 1us to 1ms.
