Before this commit 3 sensors were reported, but they were not actually
functional.  After this commit the sensors are no longer reported, but
also the resume time increased.

To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

bf7660dab3 HID: stop drivers from selecting CONFIG_HID
There is a mix of drivers using either 'depends on HID' or 'select HID',
which causes both circular dependencies and missed dependencies for
a 'select':

Avoid this by changing all HID client drivers to use 'depends on HID'.
For I2C_HID, this requires a larger rework of the Kconfig description,
but it hopefully becomes easier to understand without the complex
I2C_HID_CORE definition.

25621bcc89 HID: Kconfig: split HID support and hid-core compilation
Currently, we step into drivers/hid/ based on the value of
CONFIG_HID.

However, that value is a tristate, meaning that it can be a module.

As per the documentation, if we jump into the subdirectory by
following an obj-m, we can not compile anything inside that
subdirectory in vmlinux. It is considered as a bug.

To make things more friendly to HID-BPF, split HID (the HID core
parameter) from HID_SUPPORT (do we want any kind of HID support in the
system?), and make this new config a boolean.

68266bdcce HID: amd_sfh: Handle condition of "no sensors" for SFH1.1
Based on num_hid_devices, each sensor device registers to HID. If
"no sensors" then amd_sfh work initialization and scheduling
doesn’t make sense and return ENODEV to stop driver probe.
Hence add a check for num_hid_devices to handle special
case in the situation of "no sensors" for SFH1.1.

Google Chromebooks use Chrome OS Embedded Controller Sensor Hub instead
of Sensor Hub Fusion and leaves MP2 uninitialized, which disables all
functionalities, even including the registers necessary for feature
detections.

The behavior was observed with Lenovo ThinkPad C13 Yoga.
