In the Linux kernel, the following vulnerability has been resolved:
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().
