I'm confused, I see lots of different patches here, with this final
thread looking like this:

 Apr 13 Alexandru Hossu (  51) [PATCH v2 1/2] staging: nvec: fix use-after-free in nvec_rx_completed()
 Apr 13 Alexandru Hossu (  40) └─>[PATCH v2 2/2] staging: nvec: fix unconditional pm_power_off teardown

What is patch v3 of?  What about patch 1/2?

This is really confusing.

When redoing a patch in a series, you need to resend the whole series as
a new version.  Otherwise I have no idea what to do (and our tools get
_VERY_ confused as well.)

So a v4 full series please?

thanks,
