[PATCH] HID: logitech-hidpp: select CONFIG_POWER_SUPPLY

[PATCH] HID: logitech-hidpp: select CONFIG_POWER_SUPPLY

[Arnd Bergmann]

A recent commit added barry support to this driver, but that causes
a link failure when CONFIG_POWER_SUPPLY is not set:

drivers/hid/built-in.o: In function `hidpp_battery_get_property':
:(.text+0x1a834): undefined reference to `power_supply_get_drvdata'
drivers/hid/built-in.o: In function `hidpp_raw_event':
:(.text+0x1b10c): undefined reference to `power_supply_changed'
drivers/hid/built-in.o: In function `hidpp_connect_event':
:(.text+0x1bd88): undefined reference to `devm_power_supply_register'
:(.text+0x1be30): undefined reference to `power_supply_powers'

This adds a dependency, identically to the other HID drivers that need this.

Thanks. I am pushing this to for-4.8/logitech-hidpp-battery, but I will be 
unmerging that branch from 'for-next' shortly anyway, as the whole 
patchset is currently on hold.
