3.16.74-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Brian Masney <masneyb@xxxxxxxxxxxxx> 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.
