Open Device Helper 0.4.2

Open Device Helper 0.4.2

• Bypass keeps the charger at full power: with kernel t51 or newer (charge current limit, patch 0132), Bypass
  holds the battery with a small charge current (100 mA by default) instead of lowering the charge limit, so the USB PD
  contract stays at 9 V (about 21 W) instead of dropping to 5 V (about 12 W). The battery still helps when the load is
  over what the charger gives. Battery → Bypass Method / Bypass Current in the app, tb323fu-ctl bypass method auto|current|limit and tb323fu-ctl bypass current MA; older kernels keep the old way.
• Stalled charging is restarted: when the firmware stops charging by itself below the limit, the helper starts it
  again (Battery → Restart Stalled Charging, tb323fu-ctl battery stall-rescue on|off).
• Fixed: a connected Bluetooth mouse's battery was taken for the tablet's (wrong charge and a 100 % limit in the app
  and quick settings). About shows the kernel's patch series again instead of "unknown".
