Subject: [PATCH 5.3 005/140] ASoC: topology: Fix a signedness bug in soc_tplg_dapm_widget_create()

From: Dan Carpenter <dan.carpenter@...cle.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.
