From b9f0bfd16d8b390b35dbec67c3ed74e74a0ade24 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 23 Dec 2021 13:36:24 +0200 Subject: [PATCH] ASoC: SOF: dsp_arch_ops: add kernel log level parameter for oops and stack To allow custom log level to be used for the DSP oops and stack print, add a kernel log level parameter to the two ops. Modify the xtensa oops and stack functions tom use this new log level parameter. Pass KER_ERR from snd_sof_get_status() to make sure that there is no functional change with this new parameter.
