[igt-dev] [PATCH i-g-t 2/7] Cast void * pointer used in arithmetic to uint32_t*

[Rodrigo Siqueira]

This commit fixes the GCC warning:

warning: pointer of type ‘void *’ used in arithmetic [-Wpointer-arith]
     memset(ptr + offsets[0], full_range ? 0x00 : 0x10,
                ^
warning: pointer of type ‘void *’ used in arithmetic [-Wpointer-arith]
     memset(ptr + offsets[1], 0x80,

This commit cast the ptr pointer, which is a void *, to uint32_t * in
the pointer arithmetic operation.
