Arnd Bergmann 69d3973af1 [media] ttpci: address stringop overflow warning 
gcc-7.0.1 warns about old code in ttpci:

In file included from drivers/media/pci/ttpci/av7110.c:63:0:
In function 'irdebi.isra.2',
    inlined from 'start_debi_dma' at drivers/media/pci/ttpci/av7110.c:376:3,
    inlined from 'gpioirq' at drivers/media/pci/ttpci/av7110.c:659:3:

   memcpy(av7110->debi_virt, (char *) &res, count);

   memcpy(av7110->debi_virt, (char *) &res, count);

Apparently, 'count' can be negative here, which will then get turned
into a giant size argument for memcpy. Changing the sizes to 'unsigned
int' instead seems safe as we already check for maximum sizes, and it
also simplifies the code a bit.
