Subject: [PATCH] ASoC: SOF: Intel: hda: add dev_err() traces for snd_sof_dsp_read_poll_timeout()
Git-commit: 6a414489e0f3309a221f26b3d11c19d1a96a3635
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
Such traces should be extremely rare but extremely useful for debug.
Report errors for all calls to sdn_sof_dsp_read_poll_timeout(), but
only on negative values for consistency.
Add traces that enable each timeout to be uniquely identified.
