2018-07-03leds: max8997: use mode when calling max8997_led_set_modeColin Ian King1-1/+1
Variable mode is assigned to pdata->led_pdata->mode[led->id] and yet is not being used when calling function max8997_led_set_mode. Fix this by using mode when calling max8997_led_set_mode. Cleans up clang warning: warning: variable 'mode' set but not used [-Wunused-but-set-variable] Fixes: 8584cb82f151 ("leds: Add suuport for MAX8997-LED driver") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>

2018-07-03leds: lt3593: merge functions and clean up codeDaniel Mack1-68/+35
In preparation to DT probe functionality, merge create_lt3593_led() into its only call-site. The DT based setup code will be quite different, so this internal helper function is of no help. This also changes the way the driver works by only handling one entry inside 'struct gpio_led_platform_data'. If multiple devices of the same type are found in a design, there should be a platform device for each of them. The only mainline user of this driver is not affected by this change. Last, use devm_led_classdev_register() instead of led_classdev_register(), so the driver's remove callback can go away.
