Subject: [PATCH v2 3/7] PCI: PM: Drop struct pci_platform_pm_ops
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
After previous changes there are no more users of struct
pci_platform_pm_ops in the tree, so drop it along with all of the
remaining related code.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

New patch in v2.

- *
- * @set_state: invokes the platform firmware to set the device's power state

- * @get_state: queries the platform firmware for a device's current power state

- * @refresh_state: asks the platform to refresh the device's power state data
- *
- * @choose_state: returns PCI power state of given device preferred by the
- * platform; to be used during system-wide transitions from a
- * sleeping state to the working state and vice versa
- *
- * @set_wakeup: enables/disables wakeup capability for the device
- *
- * @need_resume: returns 'true' if the given device (which is currently

- *
- * If given platform is generally capable of power managing PCI devices, all of
