[meta-ti] [PATCH] linux-ti-staging: Work around to avoid race condition with external module

[Denys Dmytriyenko]

Stefan,

Yes, indeed, thanks.


Sam,

You only picked up part of the fix:
http://cgit.openembedded.org/openembedded-core/commit/?id=afcea61e8eb39234d336c706fdfd4680dea7c060

I don't want to overlay the entire module-base.bbclass, so I guess for our 
problematic out-of-tree modules we can just add this to their recipes:

do_configure[depends] += "virtual/kernel:do_compile_kernelmodules"
