[PATCH] List LGPL (v2 / v2.1) as GPL compatible inlicense_is_gpl_compatible()

[Harald Welte]

It may be a highly unusual choice to license Linux kernel drivers under
LGPL, but at least as long as LGPLv2 or LGPLv2.1 is used, this is fully
GPL compatible and shouldn't taint the kernel.

 NOTE: I've actually seen this happen in practise, where an embedded
 system ships with a LPGL licensed driver which in turn taints the
 kernel.  I suppose this was not really the intention...
