Subject: powerpc/83xx/mpc832x_rdb: fix of_irq_to_resource() error check
Git-commit: f29bb7861a5107cc1afbf5a565c3109aa88d5984
Patch-mainline: v4.13-rc4
References: fate#326470
of_irq_to_resource() has recently been fixed to return negative error #'s
along with 0 in case of failure, however the Freescale MPC832x RDB board
code still only regards 0 as a failure indication -- fix it up.
Fixes: 7a4228bbff76 ("of: irq: use of_irq_get() in of_irq_to_resource()")
