Hi Stephen, Thanks for pointing it. It took me some time, but I applied today a bunch of patches that are fixing all warnings on everything at drivers/media and drivers/staging/media, with: make ARCH=i386 W=1 (allyesconfig, gcc 4.7.2) Maybe there are still a few ones with random configs and other archs, but at least on my usual testing environment, we're warnings-free on drivers/media for now, probably up to the next gcc version. -- Regards, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
