Move the common part of pnp_init_resource_table() and
pnp_clean_resource_table() into a new pnp_init_resource().
This reduces a little code duplication and will be
useful later to initialize an individual resource.
This can't be right, can it? :
+void pnp_init_resource(struct resource *res)
+{
+ unsigned long type;
+
+ type = res->flags & (IORESOURCE_IO | IORESOURCE_MEM |
+ IORESOURCE_IRQ | IORESOURCE_DMA);
+
+ res->name = NULL;
+ res->flags = type | IORESOURCE_AUTO | IORESOURCE_UNSET;
+ if (type == IORESOURCE_IRQ || type == IORESOURCE_DMA) {
+ res->start = -1;
+ res->end = -1;
+ } else {
+ res->start = 0;
+ res->end = 0;
+ }
+}
This depends on the type already being set in res->flags, yet:

... it's not being set.
