From 965e49cdf8c19f21b8308adeded3a8139cff5c84 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 9 Apr 2024 14:00:33 +0300 Subject: ASoC: SOF: ipc4-pcm: Use consistent name for snd_sof_pcm_stream pointer Throughout the file the pointer for snd_sof_pcm_stream is named either 'stream' or (wrongly) 'spcm' which confuses the reader. Use 'sps' for the pointer name as it is the most common name used in SOF codebase.
