Gregory CLEMENT says:

====================
Few mvneta fixes

In this second version I split the last patch in two parts as
requested.

For the record the initial cover letter was:
"here is a patch set of few fixes. Without the first one, a kernel
configured with debug features ended to hang when the driver is built
as a module and is removed. This is quite is annoying for debugging!

The second patch fix a forgotten flag at the initial submission of the
driver.

The third patch is only really a cosmetic one so I have no problem to
not apply it for 4.5 and wait for 4.6.

I really would like to see the first one applied for 4.5 and for the
second I let you judge if it something needed for now or that should
wait the next release."
