[PATCH 5.8 233/633] coresight: etm4x: Fix issues within reset interface of sysfs

[Greg Kroah-Hartman]

From: Jonathan Zhou <jonathan.zhouwen@xxxxxxxxxx>

[ Upstream commit 4020fc8d4658dc1dbc27c5644bcb6254caa05e5e ]

The member @nr_addr_cmp is not a bool value, using operator '>'
instead to avoid unexpected failure.

Fixes: a77de2637c9e ("coresight: etm4x: moving sysFS entries to a dedicated file")
