Hi Axel,
Thanks for catching this. I missed also redundant devm_kfree here.
Would it be OK for you if I merged your cleanup with the original
patch and added your Reviewed-by to the commit message instead?
This driver hasn't been pushed to the mainline yet, so it would be
nice not to introduce its original version with some shortcomings
that need to be immediately fixed.
Best regards,
Jacek Anaszewski

The LP3952_LED_ALL is known at compile time, so we can just store
leds[LP3952_LED_ALL] in struct lp3952_led_array rather than calling
devm_kcalloc() to allocate the memory.
