[PATCH 5.19 205/717] leds: lm3601x: Dont use mutex after it was destroyed

[Greg Kroah-Hartman]

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit 32f7eed0c763a9b89f6b357ec54b48398fc7b99e ]

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")
