3.16.74-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Brian Masney <masn...@onstation.org>
commit d3f48ec0954c6aac736ab21c34a35d7554409112 upstream.
lm3630a_bank_a_update_status() and lm3630a_bank_b_update_status()
both return the brightness value if the brightness was successfully
updated. Writing to these attributes via sysfs would cause a 'Bad
address' error to be returned. These functions should return 0 on
success, so let's change it to correct that error.
