[PATCH] dns323-setup.c: fix WARN() when booting

[Arnaud Patard (Rtp)]

Since commit b2a731aa5cbca7e0252da75e16de7ae5feb1313a, dns323_init() is
setting the power led gpio direction with gpio_direction_output() but
doesn't request the gpio before (which is not permitted by the gpio
layer afaik). This behaviour is triggering a WARN() at boot time.
