leds-lp5523: BUG() in error handling in probe()
Inside the error handling in lp5523_init_led(), there is a place that
calls to led_classdev_unregister(). When we unregister the LED drivers,
it tries to set the brightness to OFF. In this driver setting the
brightness is done through a work queue and the work queue hasn't been
initialized yet.
The result is that we trigger a WARN_ON() in the __queue_work().
The fix is to move the INIT_WORK() in front of the call to
lp5523_init_led().
Matt Renzelmann found this using a bug finding tool.
