[PATCH AUTOSEL 4.20 111/304] ARM: dts: aspeed: add missing memory unit-address

[PATCH AUTOSEL 4.20 111/304] ARM: dts: aspeed: add missing memory unit-address

[Sasha Levin]

From: Rob Herring <robh@kernel.org>

[ Upstream commit 8ef86955fe59f7912a40d57ae4c6d511f0187b4d ]

The base aspeed-g5.dtsi already defines a '/memory@80000000' node, so
'/memory' in the board files create a duplicate node. We're probably
getting lucky that the bootloader fixes up the memory node that the
kernel ends up using. Add the unit-address so it's merged with the base
node.

Found with DT json-schema checks.

[PATCH AUTOSEL 4.20 158/304] cpuidle: big.LITTLE: fix refcount leak

[Sasha Levin]

From: Yangtao Li <tiny.windzz@gmail.com>

[ Upstream commit 9456823c842f346c74265fcd98d008d87a7eb6f5 ]

of_find_node_by_path() acquires a reference to the node
returned by it and that reference needs to be dropped by its caller.
bl_idle_init() doesn't do that, so fix it.
