[PATCH] sparc: add missing put_device()

[sunran001@xxxxxxxxxx]

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.

./arch/sparc/kernel/of_device_common.c:36:1-7: ERROR: missing
put_device; call of_find_device_by_node on line 30, but without a
corresponding object release within this function.
./arch/sparc/kernel/of_device_common.c:50:1-7: ERROR: missing
put_device; call of_find_device_by_node on line 42, but without a
corresponding object release within this function.
