No it is not the requirement, when I downloaded the source "4.0.5-rc7+" was
latest. Is there any problem with 4.0.5-rc7+?

I do not understand these two sentences.

You said you tried to load a module built for the 4.0.5-rc7 kernel tree
(which is a very odd kernel version number, as I don't recall ever
making a -rc7 for 4.0.5, which was released way back in June of 2015,
but that's another issue...) In order to do that properly, you have to
be running that specific kernel version at the same time so this will
work properly.

So, what specific kernel version are you currently running?  Does it
match up with the kernel version of the module you are wanting to load?
(exercise for exactly how to determine both of these is left for the
reader...)
