From 29aab38823b61e482995c24644bd2d8acfe56185 Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Tue, 7 Feb 2023 17:04:24 +0800 Subject: [PATCH] ASoC: fsl_sai: fix getting version from VERID The version information is at the bit31 ~ bit16 in the VERID register, so need to right shift 16bit to get it, otherwise the result of comparison "sai->verid.version >= 0x0301" is wrong.
