You might want to take a look. Changes in v3: - Add Thomas' RB. 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.
