This has already been (sort of) reported on vboxusers - while trying to see if
new SVN releases fix my compiling problem in the 5.0 series (manual.pdf be
damned :( ), I advanced both kernel to 4.3-rc1 and SVN to 57718.
Relevant background:
https://lkml.org/lkml/2015/7/30/815
Proposed (possibly too conservative, using preprocessor directives to condition
compilation based on KERNEL_VERSION check) patch to ignore the
misc_deregister reportedly useless return code is attached.
thanks,
