+Subject: i2c: acpi: fix resource leak in reconfiguration device addition
+
+From: Jamie Iles <quic_jiles@quicinc.com>
+
+[ Upstream commit 6558b646ce1c2a872fe1c2c7cb116f05a2c1950f ]
+
+acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a
+reference on the adapter which is never released which will result in a
+reference count leak and render the adapter unremovable.  Make sure to
+put the adapter after creating the client in the same manner that we do
+for OF.
