Remove the hpc_ops struct from shpchp. This struct is unnecessary as
no other hotplug controller implements it. A similar thing has already
been done in pciehp with commit 82a9e79ef132 ("PCI: pciehp: remove hpc_ops")
Signed-off-by: ngn <ngn@xxxxxx>
---
Changes in v2:
- Fix a few typos
- Remove hpc_ops from the slot and the controller struct
Changes in v3:
- Update the commit message according to the Bjorn's response
- Remove the related task from the TODO file

shpchp:
-* There is only a single implementation of struct hpc_ops. Can the struct be
- removed and its functions invoked directly? This has already been done in
- pciehp with commit 82a9e79ef132 ("PCI: pciehp: remove hpc_ops"). Clarify
- if there was a specific reason not to apply the same change to shpchp.
-
* The hardirq handler shpc_isr() queues events on a workqueue. It can be
simplified by converting it to threaded IRQ handling. Use pciehp as a
template.
