Note that android kernel is not vanilla kernel.

If you have custom kernel (e.g android kernel) with extra features backported
you need to enable support for those features in compat-drivers for
your kernel i.e. mark it as applicable for lower kernel version (comparing to
vanilla kernel which introduced this feature)

The 'proper' solution would be to have support for Android (or CM) kernel in
compat-drivers (same as eg. RH kernel would). But Android kernels varies
heavily among devices and it could be hard to support all of them. It is also
worth noting that often custom non-mainlined code doesn't even build when
configured as module e.g. bluesleep driver from grouper kernel. This is extra
obstacle as one would have to fix or disable such offending code.
