Subject: [PATCH] leds: lm3601x: Don't use mutex after it was destroyed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The mutex might still be in use until the devm cleanup callback
devm_led_classdev_flash_release() is called. This only happens some time
after lm3601x_remove() completed.
Fixes: e63a744871a3 ("leds: lm3601x: Convert class registration to device managed")
