  [PATCH] leds: leds-menf21bmc.c: Use devm_led_class_register Muhammad Falak R Wani <falakreyaz@gmail.com> - 2015-10-16 22:20 +0200

#1249136 — [PATCH] leds: leds-menf21bmc.c: Use devm_led_class_register

Use resource-managed function devm_led_classdev_register instead
of led_classdev_register, consequently remove redundant
menf21bmc_led_remove function.
Also drop the unneeded label err_free_leds.
