From 14bdc7b2f9ea0d3f86beed93079ce40a7ead57ac Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 21 Apr 2022 15:18:47 -0500 Subject: ASoC: SOF: topology: Check w->sname validity once in sof_connect_dai_widget() The 'w' (struct snd_soc_dapm_widget) is not changing within the function, there is no reason to check the w->sname more than once as it is not going to change.
