list: fix an issue with android build using clang
Sorry, I don't understand the android build system enough to say *which* version of clang this effects, but either "clang-2812033" or "clang-3016494" (probably the later). But when 'sample' is undefined (ie. unitialized variable), the result is not as well defined as it is with gcc. Instead use a typeof() cast with a defined value (ie. zero). This fixes a crash that was reported on android. Reported-by: John Stultz <> Signed-off-by: Rob Clark <>
