This bitmap can be BRCM_INT_PCI_MSI_LEGACY_NR or BRCM_INT_PCI_MSI_NR long.

Ahh.  OK.  Given this an option would be to: do nothing (keep current
status quo); allocate memory dynamically passing the "msi->nr" after it
has been set accordingly; use BRCM_INT_PCI_MSI_NR and waste a little bit
of space.

Perhaps moving to using the DECLARE_BITMAP() would be fine in this case
too, at least to match style of other drivers more closely.

Jim, Florian and Lorenzo - is this something that would be OK with you,
or you would rather keep things as they were?

I would be tempted to leave the code as-is, but if we do we are probably 
bound to seeing patches like Christophe's in the future to address the 
problem, unless we place a coverity specific comment in the source tree, 
which is probably frowned upon.

The addition of the BUILD_BUG_ON() is a good addition though.
