Re: [PATCH v1 2/3] uio_pci_generic: add MSI/MSI-X support

[kbuild test robot]

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:    got void *addr

vim +93 drivers/uio/uio_pci_generic.c

    87			if (flags & IORESOURCE_MEM) {
    88				void *addr;

    94				if (addr == NULL) {
    95					err = -EINVAL;
    96					goto fail;
    97				}
    98	
    99				info->mem[m].name = bar_names[i];
