The powercap_register_control_type() return error pointers. It never returns NULL. Fixes: 31afdd34f2b9 ("powercap: arm_scmi: Add SCMI powercap based driver") Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx> --- This functions should really clean up after itself if scmi_register() fails. I need to fix the static checker for that and then I'll come back and fix it if no one else does. drivers/powercap/arm_scmi_powercap.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/powercap/arm_scmi_powercap.c b/drivers/powercap/arm_scmi_powercap.c index ab96cf9a8604..2d505ec7ff81 100644 --- a/drivers/powercap/arm_scmi_powercap.c +++ b/drivers/powercap/arm_scmi_powercap.c @@ -519,8 +519,8 @@ static struct scmi_driver scmi_powercap_driver = { static int __init scmi_powercap_init(void) { scmi_top_pcntrl = powercap_register_control_type(NULL, "arm-scmi", NULL); - if (!scmi_top_pcntrl) - return -ENODEV; + if (IS_ERR(scmi_top_pcntrl)) + return PTR_ERR(scmi_top_pcntrl); return scmi_register(&scmi_powercap_driver); } -- 2.35.1
