[PATCH] leds: lm3556: Don't call kfree for the memory allocated by devm_kzalloc

[Axel Lin <axel.lin@gmail.com>]

The devm_* functions eliminate the need for manual resource releasing
and simplify error handling. Resources allocated by devm_* are freed
automatically on driver detach.

Thus adding kfree calls here will introduce double free bug.
