Subject: [PATCH v2 00/11] Remove implicit devres from pci_intx()
Date: Wed, 13 Nov 2024 13:41:48 +0100 [thread overview]
Message-ID: <20241113124158.22863-2-pstanner@redhat.com> (raw)
@Driver-Maintainers: Your driver might be touched by patch "Remove
devres from pci_intx()". You might want to take a look.
Changes in v2:
- Drop pci_intx() deprecation patch.
- ata: Add RB from Sergey and Niklas.
- wifi: Add AB by Kalle.
- Drop INTx deprecation patch
- Drop ALSA / hda_intel patch because pci_intx() was removed from
there in the meantime.
Changes since the RFC [1]:
- Add a patch deprecating pci{m}_intx(). (Heiner, Andy, Me)
- Add Acked-by's already given.
- Export pcim_intx() as a GPL function. (Alex)
- Drop patch for rts5280, since this driver will be removed quite
soon. (Philipp Hortmann, Greg)
- Use early-return in pci_intx_unmanaged() and pci_intx(). (Andy)
Hi all,
this series removes a problematic feature from pci_intx(). That function
sometimes implicitly uses devres for automatic cleanup. We should get
rid of this implicit behavior.
To do so, a pci_intx() version that is always-managed, and one that is
never-managed are provided. Then, all pci_intx() users are ported to the
version they need. Afterwards, pci_intx() can be cleaned up and the
users of the never-managed version be ported back to pci_intx().
This way we'd get this PCI API consistent again.
Patch "Remove devres from pci_intx()" obviously reverts the previous
patches that made drivers use pci_intx_unmanaged(). But this way it's
easier to review and approve. It also makes sure that each checked out
commit should provide correct behavior, not just the entire series as a
whole.
Merge plan for this is to enter through the PCI tree.
