From: Paul Chavent <paul.chavent@fnac.net>

When listing processes on a system with SOFT/HARD_IRQ enabled,
the name of the ethernet device is [irq/eth%d] (instead of [irq/eth0] for example).

This patch call the request_irq function after having initialized the name of the device.

    platform_get_irq() can fail...

    {} not needed here. I think checkpatch.pl should notice this.

request_irq will fail too so do we really need to check it?

    You then will get the following printed:

macb: Unable to request IRQ -6 (error -22)

    If this is acceptable, then platfrom_get_irq()'s result can be ignored indeed.
