SubjectRe: [PATCH] HID: input: fix battery level reporting on BT mice
Date
Hi Dimitry,

I reapplied the 3 commits I had to revert earlier and applied your patch. Have
correct battery level reading on my BT mouse back!

/sys/class/power_supply/hid-00:1f:20:fd:cb:be-battery# grep "" *
capacity:53
grep: device: Is a directory
model_name:Bluetooth Mouse M336/M337/M535
online:1
grep: power: Is a directory
grep: powers: Is a directory
present:1
scope:Device
status:Discharging
grep: subsystem: Is a directory
type:Battery
uevent:POWER_SUPPLY_NAME=hid-00:1f:20:fd:cb:be-battery
uevent:POWER_SUPPLY_PRESENT=1
uevent:POWER_SUPPLY_ONLINE=1
uevent:POWER_SUPPLY_CAPACITY=53
uevent:POWER_SUPPLY_MODEL_NAME=Bluetooth Mouse M336/M337/M535
uevent:POWER_SUPPLY_STATUS=Discharging
uevent:POWER_SUPPLY_SCOPE=Device

rdesc file is attached

Thx for the effort!

Best regards,
Martin van Es
