* IS31FL3733 Dirty page fix Function IS31FL3733_update_led_control_registers was never setting update register to false. As a result the led on/off page was being written every transaction even when it was not modified. This is ineficient and causes lots of bandwidth use. -> Fix the IS31FL3733_update_led_control_registers. -> After testing it was evident that failed I2C transactions could corrupt the Led on/off register. -> Update IS31FL3733_write_pwm_buffer and IS31FL3733_write_register functions to return 0 upon succesful tranmission and 1 if any of the transmitions within the function fail. -> Modify IS31FL3733_update_pwm_buffers function so if any of the IS31FL3733_write_pwm_buffer transuction fails, the g_led_control_registers_update_required register is set to true forcing a rewrite of the led on/off register in case it was corrupted. * Minor comment update * Upsie:) * Update is31fl3733.c * Return fix * more return fix * type change * more boolian logic reversal:)
