6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 2ccfe94bc3ac980d2d1df9f7a0b2c6d2137abe55 ]
The reference count is bumped by device_get_named_child_node()
and never dropped. Since LED APIs do not require it to be
bumped by the user, drop the reference after LED registration.
[andy: rewritten the commit message and amended the change]
