[PATCH 3/3] powercap: arm_scmi: Fix a NULL vs IS_ERR() bug
From: Cristian Marussi
Date: Wed Aug 17 2022 - 06:55:04 EST
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
The powercap_register_control_type() return error pointers. It never
returns NULL.
Fixes: 31afdd34f2b9 ("powercap: arm_scmi: Add SCMI powercap based driver")
