Dmitry Torokhov 2e210bbb74 HID: input: fix battery level reporting on BT mice ... The commit 581c448476 ("HID: input: map digitizer battery usage") assumed that devices having input (qas opposed to feature) report for battery strength would report the data on their own, without the need to be polled by the kernel; unfortunately it is not so. Many wireless mice do not send unsolicited reports with battery strength data and have to be polled explicitly. As a complication, stylus devices on digitizers are not normally connected to the base and thus can not be polled - the base can only determine battery strength in the stylus when it is in proximity. To solve this issue, we add a special flag that tells the kernel to avoid polling the device (and expect unsolicited reports) and set it when report field with physical usage of digitizer stylus (HID_DG_STYLUS). Unless this flag is set, and we have not seen the unsolicited reports, the kernel will attempt to poll the device when userspace attempts to read "capacity" and "state" attributes of power_supply object corresponding to the devices battery.
