Re: [PATCH v3 10/10] media: flash: use led_set_brightness_sync for torch brightness

[Jacek Anaszewski <j.anaszewski@samsung.com>]

Hi Mauro,

This patch depends on the preceding LED core improvements patches
from this patch set, and it would be best if it was merged through
the LED tree. Can I get your ack for this? I've already obtained acks
for the whole set from Sakari.

Best Regards,
Jacek Anaszewski
