  "message": "backlight: Fix external uses of backlight internal semaphore\n\nbacklight_device-\u003esem has a very specific use as documented in the\nheader file. The external users of this are using it for a different\nreason, to serialise access to the update_status() method.\n\nbacklight users were supposed to implement their own internal\nserialisation of update_status() if needed but everyone is doing\nthings differently and incorrectly. Therefore add a global mutex to\ntake care of serialisation for everyone, once and for all.\n\nLocking for get_brightness remains optional since most users don\u0027t\nneed it.\n\nAlso update the lcd class in a similar way.\n\nSigned-off-by: Richard Purdie \u003crpurdie@rpsys.net\u003e\n",
