FE_READ_SNR and FE_READ_SIGNAL_STRENGTH docs

Hi guys, I'm confused the documentation on:

http://linuxtv.org/downloads/v4l-dvb-apis/frontend_fcalls.html#FE_READ_SNR
http://linuxtv.org/downloads/v4l-dvb-apis/frontend_fcalls.html#FE_READ_SIGNAL_STRENGTH

states that these ioctls return int16_t values but frontend.h states:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/dvb/frontend.h

#define FE_READ_SIGNAL_STRENGTH  _IOR('o', 71, __u16)
#define FE_READ_SNR              _IOR('o', 72, __u16)

So which one is true?
