[PATCH] hwmon: hp-wmi-sensors: fix debugfs check

From: Arnd Bergmann
Date: Thu Jun 01 2023 - 17:32:26 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

Checking for Kconfig symbols with #if is wrong:

drivers/hwmon/hp-wmi-sensors.c:1141:5: error: "CONFIG_DEBUG_FS" is not defined, evaluates to 0 [-Werror=undef]

This could be an #ifdef, but an IS_ENABLED() check is even better to
give the best compile coverage.

Fixes: 602bef0fa281f ("hwmon: add HP WMI Sensors driver")
