[patch 12/28] PNP: define PNP-specific IORESOURCE_IO_* flags alongside IRQ, DMA, MEM

[-- Attachment #1: pnp-io-option-flags --]
[-- Type: text/plain, Size: 6059 bytes --]

PNP previously defined PNP_PORT_FLAG_16BITADDR and PNP_PORT_FLAG_FIXED
in a private header file, but put those flags in struct resource.flags
fields. Better to make them IORESOURCE_IO_* flags like the existing
IRQ, DMA, and MEM flags.
