From: Lad Prabhakar <[email protected]> platform_get_irq_byname() may return specific error codes such as -EPROBE_DEFER, but rzg3s_pcie_init_irqdomain() replaces all failures with -EINVAL. This breaks probe deferral by preventing the driver core from retrying probe once the interrupt provider becomes available. Propagate the original error code instead.
