we do not check the result of kzalloc ouch
and why we allocate it?

for both remarks : that's the way it's done in at91_add_device_mci since
75305d768d296a07fd02df9af3e5de326df1c72e
A v2 will follow (and also a fix for at91_add_device_mci).

just declare it as static

last time we had some data static and you asked to alloc them (and
didn't bother to answer why you required that :
http://lkml.indiana.edu/hypermail/linux/kernel/1207.0/02779.html ), now
you ask to declare static something which is allocated (and
that's already done this way for the mci) : may you please explain why
so that we get it the right way for next time ?
Thanks

in the driver yes we write multi instance and generic code but in the platfrom I do not see why
