Changes in v2:
Print the return value of platform_get_irq on failure.
Changes in v3:
Put back the blank line after the IF closing brace,
which was accidentally removed in v2.

this patch is wrong, I've explained why at https://lkml.org/lkml/2017/6/30/144
Please handle -EPROBE_DEFER case, when your change adds the second (redundant)
error level message printed to the kernel log.
