Bug description:
[ Impact ]
* Upstream commit:
https://gitlab.freedesktop.org/libfprint/libfprint/-/commit/eaec2339ccaee64b2bdb1d1e27f51ada673e4087
* Add new Broadcom device IDs in order to reduce the power consumption
on the target machine.
* It might consume more power if the IDs are not in the list.
[ Test Plan ]
* Install package on laptop with either IDs list below, and check USB_DEVICE/power/control
is auto or on.
* usb:v0A5Cp5860*
usb:v0A5Cp5863*
usb:v0A5Cp5864*
usb:v0A5Cp5865*
usb:v0A5Cp5866*
usb:v0A5Cp5867*
[ Where problems could occur ]
* Should be low because these IDs only affect on the machine with those Broadcom devices and it
improves the power consumption.
