For future sysfs show function patches, please use PAGE_SIZE as second
snprintf() argument or use sprintf() instead of snprintf() because in
this case it is clear that no output buffer overflow will happen. Using
any other size argument than PAGE_SIZE makes patches like the above
harder to verify than necessary. Anyway:
