Description

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().
