[PATCH] Fix compiler warning about "cast increases required alignment"
Some ISA, like ARMv6, do not support unaligned memory accesses. The cast here technically convert a the pointer target from a char to another pointer. However, as the buf field (char) is laid out after a pointer in the structure definition, the alignment for buf is forced to the same alignment as a pointer. Thus the issue with unaligned access can not happen and the workaround by re-casting the pointer via void * is safe.
[PATCH] Handle a bunch of other compiler warnings on armv6 and similararchectures that can not handle unaligned accesses and where pointer conversions cause compiler warnings when converting a pointer to a larger type.
