From 8fbc28b557794118ba373be87be29b6df5409bed Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 26 Nov 2024 15:36:28 +0200 Subject: [PATCH] ASoC: SOF: pcm: Add snd_sof_pcm specific wrappers for dev_dbg() and dev_err() Introduce spcm_dbg() and spcm_err() macros to provide consistent printing for debug and error messages which includes usable information in the print's prefix. Update the prints in pcm.c, ipc3-pcm.c and ipc4-pcm.c to take advantage of the features provided by the macros.
