[PATCH] of: irq: Fix the return value for of_irq_parse_one() stub

2021-02-10 Thread Saravana Kannan
When commit 1852ebd13542 ("of: irq: make a stub for of_irq_parse_one()")
added a stub for of_irq_parse_one() it set the return value to 0. Return
value of 0 in this instance means the call succeeded and the out_irq
pointer was filled with valid data. So, fix it to return an error value.
