PCI: pciehp: Rename duplicate slot name N as N-1, N-2, N-M...
Commit 3800345f723fd130d50434d4717b99d4a9f383c8 (pciehp: fix slot name)
introduces the pciehp_slot_with_bus module parameter, which was intended
to help work around broken firmware that assigns the same name to multiple
slots.
Commit 9e4f2e8d4ddb04ad16a3828cd9a369a5a5287009 (pciehp: add message about
pciehp_slot_with_bus option) tells the user to use the above parameter
in the event of a name collision.
This approach is sub-optimal because it requires too much work from
the user.
Instead, let's rename the slot on behalf of the user. If firmware
assigns the name N to multiple slots, then:
The first registered slot is assigned N
The second registered slot is assigned N-1
The third registered slot is assigned N-2
The Mth registered slot becomes N-M
In the event we overflow the slot->name parameter, we report an
error to the user.
This is a temporary fix until the entire PCI core can be reworked
such that individual drivers no longer have to manage their own
slot names.
