Unknown battery level for DS4 in Linux

SDL Development
1

Hello,

I have problem with reading battery level from DualShock 4 using SDL_JoystickCurrentPowerLevel

I always get SDL_JOYSTICK_POWER_UNKNOWN.
This is strange, because I can read battery level using upower

$ upower -i `upower -e | grep 'sony'`

The same code compiled under Windows works properly.
