HID: amd_sfh: if no sensors are enabled, clean up
[ Upstream commit 7bcfdab3f0c6672ca52be3cb65a0550d8b99554b ]
It was reported that commit b300667b33b2 ("HID: amd_sfh: Disable the
interrupt for all command") had caused increased resume time on HP Envy
x360.
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.
