SubjectRe: [PATCH 20/31] platform: x86: changing LED_* from enum led_brightness to actual value
From
Hi,

This change is fine with me. I assume that this depends on earlier
changes in this series (1), so that it is best to merge the entire
series through the LED tree, here is my ack for merging the
drivers/platform/x86 bits through the LED tree:

Acked-by: Hans de Goede <hdegoede@redhat.com>

Regards,

Hans

1) next time please send the entire series to
the platform-driver-x86@vger.kernel.org list and not just one patch
of a series.
