It just occurred to me that there could be another intention behind
the ioctl call. Calling ioctl(EVIOCGVERSION) on the /dev/input device
is a way for the code to verify it's actually sending messages to a
/dev/input file, vs some other file. So, while not documented in the
source code, this call may actually have value and protect the caller
from inadvertently specifying an invalid file.
