[PATCH 5.8 160/177] debugfs: Fix module state check condition

From: Greg Kroah-Hartman
Date: Tue Sep 15 2020 - 19:12:50 EST


From: Vladis Dronov <vdronov@xxxxxxxxxx>

commit e3b9fc7eec55e6fdc8beeed18f2ed207086341e2 upstream.

The '#ifdef MODULE' check in the original commit does not work as intended.
The code under the check is not built at all if CONFIG_DEBUG_FS=y. Fix this
by using a correct check.

Fixes: 275678e7a9be ("debugfs: Check module state before warning in {full/open}_proxy_open()")
