From 5f11723b204aaf461e7a5242fc732222d2f0aa17 Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Tue, 28 Jul 2020 13:24:33 -0600 Subject: PCI: switchtec: Add missing __iomem and __user tags to fix sparse warnings Fix a number of missing __iomem and __user tags in the ioctl functions of the switchtec driver. This fixes a number of sparse warnings of the form: $ make C=2 drivers/pci/switch/ drivers/pci/switch/switchtec.c:... incorrect type in ... (different address spaces) Fixes: 52eabba5bcdb ("switchtec: Add IOCTLs to the Switchtec driver") Link: https://lore.kernel.org/r/20200728192434.18993-1-logang@deltatee.com Signed-off-by: Logan Gunthorpe Signed-off-by: Bjorn Helgaas --- drivers/pci/switch/switchtec.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/drivers/pci/switch/switchtec.c b/drivers/pci/switch/switchtec.c index 850cfeb74608..3d5da7f44378 100644 --- a/drivers/pci/switch/switchtec.c +++ b/drivers/pci/switch/switchtec.c @@ -940,7 +940,7 @@ static u32 __iomem *event_hdr_addr(struct switchtec_dev *stdev, size_t off; if (event_id < 0 || event_id >= SWITCHTEC_IOCTL_MAX_EVENTS) - return ERR_PTR(-EINVAL); + return (u32 __iomem *)ERR_PTR(-EINVAL); off = event_regs[event_id].offset; @@ -948,10 +948,10 @@ static u32 __iomem *event_hdr_addr(struct switchtec_dev *stdev, if (index == SWITCHTEC_IOCTL_EVENT_LOCAL_PART_IDX) index = stdev->partition; else if (index < 0 || index >= stdev->partition_count) - return ERR_PTR(-EINVAL); + return (u32 __iomem *)ERR_PTR(-EINVAL); } else if (event_regs[event_id].map_reg == pff_ev_reg) { if (index < 0 || index >= stdev->pff_csr_count) - return ERR_PTR(-EINVAL); + return (u32 __iomem *)ERR_PTR(-EINVAL); } return event_regs[event_id].map_reg(stdev, off, index); @@ -1057,11 +1057,11 @@ static int ioctl_event_ctl(struct switchtec_dev *stdev, } static int ioctl_pff_to_port(struct switchtec_dev *stdev, - struct switchtec_ioctl_pff_port *up) + struct switchtec_ioctl_pff_port __user *up) { int i, part; u32 reg; - struct part_cfg_regs *pcfg; + struct part_cfg_regs __iomem *pcfg; struct switchtec_ioctl_pff_port p; if (copy_from_user(&p, up, sizeof(p))) @@ -1104,10 +1104,10 @@ static int ioctl_pff_to_port(struct switchtec_dev *stdev, } static int ioctl_port_to_pff(struct switchtec_dev *stdev, - struct switchtec_ioctl_pff_port *up) + struct switchtec_ioctl_pff_port __user *up) { struct switchtec_ioctl_pff_port p; - struct part_cfg_regs *pcfg; + struct part_cfg_regs __iomem *pcfg; if (copy_from_user(&p, up, sizeof(p))) return -EFAULT; -- cgit v1.2.3
