As reported by Dan,
commit d2d10ede04b1 ("mtd: rawnand: Add Loongson-1 NAND Controller
Driver"), leads to the following Smatch static checker warning:
drivers/mtd/nand/raw/loongson1-nand-controller.c:730 ls1x_nand_chip_init()
warn: inconsistent refcounting 'chip_np->kobj.kref.refcount.refs.counter':
Fix this issue by calling of_node_put() immediately after using chip_np.
In addition, remove all unnecessary of_node_put(chip_np) calls.

The "desc" variable is NULL and PTR_ERR(NULL) is zero/success. Return
a negative error code instead.
