Subject: [PATCH v3 0/9] PCI: Remove pcim_iounmap_regions()

Changes in v3:
  - fpga/dfl-pci.c: remove now surplus wrapper around
    pcim_iomap_region(). (Andy)
  - block: mtip32xx: remove now surplus label. (Andy)
  - vdpa: solidrun: Bugfix: Include forgotten place where stack UB
    occurs. (Andy, Christophe)
  - Some minor wording improvements in commit messages. (Me)

Changes in v2:
  - Add a fix for the UB stack usage bug in vdap/solidrun. Separate
    patch, put stable kernel on CC. (Christophe, Andy).
  - Drop unnecessary pcim_release_region() in mtip32xx (Andy)
  - Consequently, drop patch "PCI: Make pcim_release_region() a public
    function", since there's no user anymore. (obsoletes the squash
    requested by Damien).
  - vdap/solidrun:
    • make 'i' an 'unsigned short' (Andy, me)
    • Use 'continue' to simplify loop (Andy)
    • Remove leftover blank line
  - Apply given Reviewed- / acked-bys (Andy, Damien, Bartosz)


Important things first:
This series is based on [1] and [2] which Bjorn Helgaas has currently
queued for v6.12 in the PCI tree.

This series shall remove pcim_iounmap_regions() in order to make way to
remove its brother, pcim_iomap_regions().

@Bjorn: Feel free to squash the PCI commits.

Regards,
P.
