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; }
