Can we convert them all at once to consolidate reviewing them? Or are the others harder so we have to do this piece-meal? > Signed-off-by: Philipp Stanner <pstanner@redhat.com> > --- > drivers/pci/devres.c | 3 ++- > include/linux/pci.h | 1 + > 2 files changed, 3 insertions(+), 1 deletion(-) > > diff --git a/drivers/pci/devres.c b/drivers/pci/devres.c > index 3780a9f9ec00..0ec2b23e6cac 100644 > --- a/drivers/pci/devres.c > +++ b/drivers/pci/devres.c > @@ -932,7 +932,7 @@ static void pcim_release_all_regions(struct pci_dev *pdev) > * desired, release individual regions with pcim_release_region() or all of > * them at once with pcim_release_all_regions(). > */ > -static int pcim_request_all_regions(struct pci_dev *pdev, const char *name) > +int pcim_request_all_regions(struct pci_dev *pdev, const char *name) > { > int ret; > int bar; > @@ -950,6 +950,7 @@ static int pcim_request_all_regions(struct pci_dev *pdev, const char *name) > > return ret; > } > +EXPORT_SYMBOL(pcim_request_all_regions); > > /** > * pcim_iomap_regions_request_all - Request all BARs and iomap specified ones > diff --git a/include/linux/pci.h b/include/linux/pci.h > index 4cf89a4b4cbc..5b5856ba63e1 100644 > --- a/include/linux/pci.h > +++ b/include/linux/pci.h > @@ -2289,6 +2289,7 @@ static inline void pci_fixup_device(enum pci_fixup_pass pass, > struct pci_dev *dev) { } > #endif > > +int pcim_request_all_regions(struct pci_dev *pdev, const char *name); > void __iomem *pcim_iomap(struct pci_dev *pdev, int bar, unsigned long maxlen); > void pcim_iounmap(struct pci_dev *pdev, void __iomem *addr); > void __iomem * const *pcim_iomap_table(struct pci_dev *pdev); > -- > 2.45.2 >

In order to remove the deprecated function pcim_iomap_regions_request_all(), a few drivers need an interface to request all BARs a PCI-Device offers. Make pcim_request_all_regions() a public interface.
