When calling request_irq with IRQF_SHARED, the dev cookie must be set
(i.e. non-NULL), otherwise the code rejects it immediately with -EINVAL.
So restore the logic here where we'd pass a pointer to the name as a
dummy unique val.
Otherwise, booting up on my LANDISK system would fail with:
DMAC Address Error0 request_irq fail
