From 99c1e74f25d435c1c714b8ee0dceb7ebb7d2f2f1 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 2 Mar 2022 09:34:25 +0100 Subject: [PATCH] ASoC: fsl_sai: store full version instead of major/minor The driver tests for the hardware revision being newer than 3.1 with (sai->verid.major >= 3 && sai->verid.minor >= 1). The result is obviously wrong for hardware revision 4.0. Fix this by storing the full version in a single variable and comparing to that one. No practical change at the moment as there is no 4.0 ip version currently.
