Both drivers cast resource_type_t to void * causing the build to fail. With CONFIG_X86_PAE enabled the resource_size_t type is a 64bit unsigned int which cannot be cast to a 32 bit pointer. Use ioremap() instead of pci_resource_start() Reported_by: Guenter Roeck <linux@xxxxxxxxxxxx> Link: https://lore.kernel.org/all/f10e976e-7a04-4454-b38d-39cd18f142da@xxxxxxxxxxxx/ Fixes: bb1bd92fa0f2 ("staging: gpib: Add ines GPIB driver") Fixes: e1339245eba3 ("staging: gpib: Add Computer Equipment Corporation GPIB driver") Signed-off-by: Dave Penkler <dpenkler@xxxxxxxxx> --- drivers/staging/gpib/cec/cec_gpib.c | 3 ++- drivers/staging/gpib/ines/ines_gpib.c | 4 ++-- 2 files changed, 4 insertions(+), 3 deletions(-) diff --git a/drivers/staging/gpib/cec/cec_gpib.c b/drivers/staging/gpib/cec/cec_gpib.c index 3dc933deb401..a1ea4d9e370a 100644 --- a/drivers/staging/gpib/cec/cec_gpib.c +++ b/drivers/staging/gpib/cec/cec_gpib.c @@ -297,7 +297,8 @@ int cec_pci_attach(gpib_board_t *board, const gpib_board_config_t *config) cec_priv->plx_iobase = pci_resource_start(cec_priv->pci_device, 1); pr_info(" plx9050 base address 0x%lx\n", cec_priv->plx_iobase); - nec_priv->iobase = (void *)(pci_resource_start(cec_priv->pci_device, 3)); + nec_priv->iobase = ioremap(pci_resource_start(cec_priv->pci_device, 3), + pci_resource_start(cec_priv->pci_device, 3)); pr_info(" nec7210 base address 0x%p\n", nec_priv->iobase); isr_flags |= IRQF_SHARED; diff --git a/drivers/staging/gpib/ines/ines_gpib.c b/drivers/staging/gpib/ines/ines_gpib.c index 9d8387c3bf01..b5f8ea57fd9d 100644 --- a/drivers/staging/gpib/ines/ines_gpib.c +++ b/drivers/staging/gpib/ines/ines_gpib.c @@ -780,8 +780,8 @@ static int ines_common_pci_attach(gpib_board_t *board, const gpib_board_config_t if (pci_request_regions(ines_priv->pci_device, "ines-gpib")) return -1; - nec_priv->iobase = (void *)(pci_resource_start(ines_priv->pci_device, - found_id.gpib_region)); + nec_priv->iobase = ioremap(pci_resource_start(ines_priv->pci_device, found_id.gpib_region), + pci_resource_len(ines_priv->pci_device, found_id.gpib_region)); ines_priv->pci_chip_type = found_id.pci_chip_type; nec_priv->offset = found_id.io_offset; -- 2.46.2
