So, I'll be applying just the CodingStyle fixes on it. Sorry, but I think you got it wrong. The example is called "mmap() example". But I did not change return value checking of mmap() calls. I changed return value checking of ioctl() calls. So I believe the patch is correct. -- Best regards, Pawel Osciak -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
