Subject[PATCH 15/16] of: unittest: initialize args before calling of_irq_parse_one()
Date
From: Frank Rowand <frank.rowand@sony.com>

Callers of of_irq_parse_one() blindly use the pointer args.np
without checking whether of_irq_parse_one() had an error and
thus did not set the value of args.np. Initialize args to
zero so that using the format "%pOF" to show the value of
args.np will show "(null)" when of_irq_parse_one() has an
error and does not set args.np instead of trying to
dereference a random value.
