  - net: emac: Fix NULL pointer dereference in emac_probe Move devm_request_irq() after
    devm_platform_ioremap_resource() so that dev->emacp is mapped before the interrupt handler can fire. An
    early interrupt hitting emac_irq() would dereference the NULL dev->emacp and crash. Also remove redundant
    error message. devm_platform_ioremap_resource() already returns an error message with dev_err_probe().
