[patch 20/28] PNP: centralize resource option allocations

Bjorn Helgaas
2008-06-27T23:10:22Z

[-- Attachment #1: pnp-centralize-option-allocs --]
[-- Type: text/plain, Size: 23086 bytes --]

This patch moves all the option allocations (pnp_mem, pnp_port, etc)
into the pnp_register_{mem,port,irq,dma}_resource() functions. This
will make it easier to rework the option data structures.

The non-trivial part of this patch is the IRQ handling. The backends
have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass
a pointer to pnp_register_irq_resource().
