SubjectWarnings on void* arithmetic
Hi...

Building the nVidia driver gives this couple warnings. I send them just
to see if they are real bugs or not.

include/linux/prefetch.h: In function ‘prefetch_range’:
include/linux/prefetch.h:62: warning: pointer of type ‘void *’ used in arithmetic

static inline void prefetch_range(void *addr, size_t len)
^^^^^^
{
#ifdef ARCH_HAS_PREFETCH
char *cp;
char *end = addr + len; <<<<<<<<<<<<<

for (cp = addr; cp < end; cp += PREFETCH_STRIDE)
prefetch(cp);
#endif
}


include/asm/io.h: In function ‘check_signature’:
include/asm/io.h:258: warning: wrong type argument to increment

static inline int check_signature(volatile void __iomem * io_addr,
^^^^^^^^^^^^^^
const unsigned char *signature, int length)
{
int retval = 0;
do {
if (readb(io_addr) != *signature)
goto out;
io_addr++; <<<<<<<<<<<<<<<<<<<
signature++;
length--;
} while (length);
retval = 1;
out:
return retval;
}
