   4 Subject: [PATCH] leds: lp55xx: Initialize enable GPIO direction to output
   5
   6 The "Convert to use GPIO descriptors" commit changed the
   7 initialization of the enable GPIO from GPIOF_DIR_OUT to
   8 GPIOD_ASIS.  This breaks systems where the GPIO does not
   9 default to output.  Changing the enable initialization
  10 to GPIOD_OUT_LOW.
