Subject: [PATCH V4 5/7] PCI: Deprecate pci_reset_bus() and pci_reset_slot() functions
Date:   Thu, 28 Jun 2018 15:31:03 -0400

Precedence: bulk

pci_reset_bus() and pci_reset_slot() functions are not being used by
any code. Remove them from the kernel in favor of pci_try_reset_bus()
and pci_try_reset_slot() functions.
