Three update suggestions were taken into account
from static source code analysis.

Markus Elfring (3):
  Add missing put_device() calls
  Use common error handling code
  Return directly after a failed devm_kzalloc()

A coccicheck run provided information like the following.

drivers/net/ethernet/freescale/fman/mac.c:874:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 659, but without a corresponding
object release within this function.
drivers/net/ethernet/freescale/fman/mac.c:874:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 760, but without a corresponding
object release within this function.

Generated by: scripts/coccinelle/free/put_device.cocci

Thus adjust jump targets to fix the exception handling for this
function implementation.
