[PATCH v4 0/5] PCI: dwc: Support remove

[Jisheng Zhang]

Currently, the PCI dwc host users don't support the remove, but nothing
prevent us from supporting it. To achieve this goal, we need to ensure
we can do necessary clean up work.

Changes since v3:
  - add Gustavo's ACK to patch2, patch5
  - remove IS_ENABLED(CONFIG_PCI_MSI) check

Changes since v2:
  - address all Gustavo's comments
  - add Gustavo's ACK to patch1, patch3, patch4

Changes since v1:
  - address Bjorn's comments, I.E Capitalize, s/irq/IRQ/, s/msi/MSI/


Jisheng Zhang (5):
  PCI: dwc: Fix dw_pcie_free_msi() if msi_irq is invalid
  PCI: dwc: Free the page for MSI IRQ in dw_pcie_free_msi()
  PCI: dwc: Free MSI in the error code path of dw_pcie_host_init()
  PCI: dwc: Use devm_pci_alloc_host_bridge() to simplify the code
  PCI: dwc: Save root bus for driver remove
