hwmon: (scmi) return -EINVAL when sensor information is unavailable
Passing NULL pointer to PTR_ERR will result in return value of 0 indicating success which is clearly not what it is intended here. This patch returns -EINVAL instead when the sensor information is not available. Fixes: b23688aefb8b ("hwmon: add support for sensors exported via ARM SCMI") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Guenter Roeck <linux@roeck-us.net> Cc: linux-hwmon@vger.kernel.org Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
