platform_get_irq() returns an error code, but the intel_mid_powerbtn
driver ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Print error message and propagate the return value of platform_get_irq
on failure.
This issue was detected with the help of Coccinelle.
