Note, the resource may be requested, OR mapped, OR both. In accordance with the naming above I assume that this is not equivalent change with potential breakages. > - cptpf->reg_base = pcim_iomap_table(pdev)[PCI_PF_REG_BAR_NUM]; > + /* Map PF's configuration registers */ > + cptpf->reg_base = pcim_iomap(pdev, PCI_PF_REG_BAR_NUM, 0); > + if (!cptpf->reg_base) { > + err = -ENOMEM; > + dev_err(dev, "Couldn't ioremap PCI resource 0x%x\n", err); > + goto clear_drvdata; > + } (Yes, I see this). ... > --- a/drivers/crypto/marvell/octeontx2/otx2_cptvf_main.c > +++ b/drivers/crypto/marvell/octeontx2/otx2_cptvf_main.c Ditto. here.

pcim_iomap_table() and pcim_iomap_regions_request_all() have been deprecated by the PCI subsystem in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). Replace these functions with their successors, pcim_iomap() and pcim_request_all_regions() Signed-off-by: Philipp Stanner <pstanner@redhat.com> --- drivers/crypto/marvell/octeontx2/otx2_cptpf_main.c | 14 +++++++++----- drivers/crypto/marvell/octeontx2/otx2_cptvf_main.c | 13 +++++++++---- 2 files changed, 18 insertions(+), 9 deletions(-)
