Subject[PATCH 5.3 005/140] ASoC: topology: Fix a signedness bug in soc_tplg_dapm_widget_create()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit 752c938a5c14b8cbf0ed3ffbfa637fb166255c3f ]

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.

Fixes: 8a9782346dcc ("ASoC: topology: Add topology core")
