6e636a0a28 leds: bcm6358: merge bcm6358_led_mode and bcm6358_led_set
bcm6358_led_mode is now only called by bcm6358_led_set, so merge both
in one single function.

93a708dab8 leds: bcm6358: remove unneded lock when checking initial LED status
This lock isn't really needed, since we're only reading the register and
changes made to other LEDs aren't relevant.

42273caa18 leds: bcm6358: Use bcm6358_led_set() in order to get rid of the lock
Replaces bcm6358_led_mode with bcm6358_led_set so we don't need to handle
the lock.

4b6ba5e28b leds: bcm6358: add missing of_node_put
for_each_available_child_of_node performs an of_node_get on each
iteration, so a break out of the loop requires an of_node_put.

A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
@@

 for_each_available_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }
// </smpl>

alias information is not created so module autoloading won't work.
