[PATCH v2 0/5] PCI: dwc: improve msi handling

[Jisheng Zhang]

Improve the msi code:
1. Add proper error handling.
2. Move dw_pcie_msi_init() from each users to designware host to solve
msi page leakage in resume path.

Since v1:
  - add proper error handling patches.
  - solve the msi page leakage by moving dw_pcie_msi_init() from each
    users to designware host


Jisheng Zhang (5):
  PCI: dwc: Call dma_unmap_page() before freeing the msi page
  PCI: dwc: Check alloc_page() return value
  PCI: dwc: Rename dw_pcie_free_msi to dw_pcie_msi_deinit
  PCI: dwc: Skip PCIE_MSI_INTR0* programming if MSI is disabled
  PCI: dwc: Move dw_pcie_msi_init() from each users to designware host
