| Subject: ASoC: cs4271: Increase delay time after reset |
| |
| From: Pascal Huerst <pascal.huerst@gmail.com> |
| |
| commit 74ff960222d90999508b4ba0d3449f796695b6d5 upstream. |
| |
| 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. |
