Please disable git move detection for this patch in v2.
This only applies when moving drivers out of staging (and possibly only
me who asks for it then ;).  The point is to allow full review of the
driver we are actually moving.  That is hard to do if we don't have
the code in the email.

Anyhow, good work on the series in general. I look forward to V2.
