Sudeep Holla	c09880cef7	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.

Sudeep Holla	b23688aefb	hwmon: add support for sensors exported via ARM SCMI ... Create a driver to add support for SoC sensors exported by the System Control Processor (SCP) via the System Control and Management Interface (SCMI). The supported sensor types is one of voltage, temperature, current, and power. The sensor labels and values provided by the SCP are exported via the hwmon sysfs interface.
