Subject: [PATCH] ASoC: topology: Fix a signedness bug in soc_tplg_dapm_widget_create()
Git-commit: 752c938a5c14b8cbf0ed3ffbfa637fb166255c3f
Patch-mainline: v5.4-rc5
References: jsc#SLE-16518 bnc#1151927 5.3.10
The "template.id" variable is an enum and in this context GCC will
treat it as an unsigned int so it can never be less than zero.
