platform_get_irq() returns an error code, but the sata_highbank driver ignores it and always returns -EINVAL. This is not correct, and prevents -EPROBE_DEFER from being propagated properly. Also, notice that platform_get_irq() no longer returns 0 on error.
Print error message and propagate the return value of platform_get_irq on failure. Signed-off-by: Gustavo A. R.
