binfmt_elf: Uninitialized variable
load_elf_interp() has interp_map_addr carefully described as "uninitialized_var" and marked so as to avoid a warning. However if you trace the code it is passed into load_elf_interp and then this value is checked against NULL. As this return value isn't used this is actually safe but it freaks various analysis tools that see un-initialized memory addresses being read before their value is ever defined. Set it to NULL as a matter of programming good taste if nothing else Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
