From 3fd391fb7c97ab6dfb9e44926a265566d1d1ab79 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 16 Apr 2018 00:38:13 +0000 Subject: [PATCH] ASoC: rsnd: ssi: wait maximum 5ms for status check It is waiting udelay(50) x 1024 (= 50ms) for status check in worst case, but it is overkill. And we shouldn't use udelay() for 50us (linux/Documentation/timers/timers-howto.txt) Waiting maximum udelay(5) x 1024 (= 5ms) is very enough for status check. This patch fixes these issue.
