1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: David S. Miller <davem@davemloft.net>
