Hi Vlad,
[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
>> drivers/uio/uio_pci_generic.c:93:30: sparse: incorrect type in assignment (different address spaces)
drivers/uio/uio_pci_generic.c:93:30: expected void *addr
drivers/uio/uio_pci_generic.c:93:30: got void [noderef] <asn:2>*
>> drivers/uio/uio_pci_generic.c:101:52: sparse: incorrect type in assignment (different address spaces)
drivers/uio/uio_pci_generic.c:101:52: expected void [noderef] <asn:2>*internal_addr
drivers/uio/uio_pci_generic.c:101:52: got void *addr
vim +93 drivers/uio/uio_pci_generic.c
87 if (flags & IORESOURCE_MEM) {
88 void *addr;
89
90 if (m >= MAX_UIO_MAPS)
91 continue;
92
> 93 addr = ioremap(start, len);
94 if (addr == NULL) {
95 err = -EINVAL;
96 goto fail;
97 }
98
99 info->mem[m].name = bar_names[i];
100 info->mem[m].addr = start;
> 101 info->mem[m].internal_addr = addr;
102 info->mem[m].size = len;
103 info->mem[m].memtype = UIO_MEM_PHYS;
104 ++m;
