Quite a series...
[patch 01/37] ISAPNP: move config register addresses out of isapnp.h
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 02/37] PNPACPI: continue after _CRS and _PRS errors
No opinion.
[patch 03/37] PNP: make pnp_add_id() internal to PNP core
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 04/37] PNP: change pnp_add_id() to allocate its own pnp_id structures
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 05/37] PNP: add pnp_eisa_id_to_string()
+void pnp_eisa_id_to_string(u32 id, char *str)
+{
+ id = be32_to_cpu(id);
+ str[0] = '@' + ((id >> 26) & 0x1f);

I'd much prefer 'A' - 1 over '@'. While no doubt not a practical issue,
it's more portable that way and more importantly, clearer.
By the way, the original isapnp_parse_id explicitly encodes the top _6_
bits in str[0] (& 0x3f) which seems odd. Bit 31 had better be 0 indeed,
but I wonder why the original didn't just assume such.
Other than that,

[patch 06/37] PNP: add pnp_alloc_dev()
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 07/37] PNP: make pnp_add_card_id() internal to PNP core
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 08/37] PNP: change pnp_add_card_id() to allocate its own pnp_id
structures
Same problem with hexadecimal as before. Bisection would get a bogus
card id here, but fixed in 09/37.

[patch 10/37] PNP: add pnp_alloc_card()
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 11/37] PNPACPI: pnpacpi_encode_ext_irq() wrongly set "irq" instead of
"extended_irq"
No opinion.
[patch 12/37] PNPACPI: use temporaries to reduce repetition

pnp_clean_resource_table interface

[patch 21/37] PNP: make generic pnp_add_dma_resource()
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 22/37] PNP: make generic pnp_add_io_resource()
int pnp_add_io_resource(..., resource_size_t len, ...)

len is a u32 or u64, so (len <= 0) == (len == 0)

[patch 23/37] PNP: make generic pnp_add_mem_resource()
1: Same comment for pnp_add_mem_resource as 22/37
2: There are 4 tests for ACPI_READ_WRITE_MEMORY here which are turned
into IORESOURCE_MEM_WRITEABLE or 0. Not sure, but should they be
turned into IORESOURCE_MEM_WRITEABLE or IORESOURCE_READONLY?
Otherwise and if not,

[patch 29/37] PNP: convert encoders to use pnp_get_resource(), not
pnp_resource_table
Acked-By: Rene Herman <rene.herman@...il.com>
[patch 30/37] PNP: convert resource accessors to use pnp_get_resource(), not
pnp_resource_table
Is there a reason to not make pnp_{port,mem,irq,dma}_{start,end,flags}()
inlines?
static inline resource_size_t pnp_port_start(struct pnp_dev *dev,
unsigned int bar)
{
struct resource *res = pnp_get_resource(dev, IORESOURCE_IO, bar);
return res->start;
}
and so on.
Also, you have pnp_{port,mem,irq,dma}_valid() returning a resource_size_t.
They should return int, I presume.
