-Subject: clocksource/drivers/timer-ti-dm: Fix child node refcount handling
-
-From: Javier Carrasco <javier.carrasco.cruz@gmail.com>
-
-[ Upstream commit e5cfc0989d9a2849c51c720a16b90b2c061a1aeb ]
-
-of_find_compatible_node() increments the node's refcount, and it must be
-decremented again with a call to of_node_put() when the pointer is no
-longer required to avoid leaking the resource.
-
-Instead of adding the missing calls to of_node_put() in all execution
-paths, use the cleanup attribute for 'arm_timer' by means of the
-__free() macro, which automatically calls of_node_put() when the
-variable goes out of scope.

-Subject: KVM: arm64: vgic-its: Clear DTE when MAPD unmaps a device
-
-From: Kunkun Jiang <jiangkunkun@huawei.com>
-
-commit e9649129d33dca561305fc590a7c4ba8c3e5675a upstream.
-
-vgic_its_save_device_tables will traverse its->device_list to
-save DTE for each device. vgic_its_restore_device_tables will
-traverse each entry of device table and check if it is valid.
-Restore if valid.
-
-But when MAPD unmaps a device, it does not invalidate the
-corresponding DTE. In the scenario of continuous saves
-and restores, there may be a situation where a device's DTE
-is not saved but is restored. This is unreasonable and may
-cause restore to fail. This patch clears the corresponding
-DTE when MAPD unmaps a device.
