Yes please.

There are a few reasons for that:
- it takes more time to actually edit your commit message when
applying it, and this way I am actually testing your commit, not the
edited one
- it also means I have to remember that I need to fix up the commit
message (while if you send an updated version, you ensure that I will
not forget about it)
- it's a one patch series, so we can just have a look at the v2 (it
would have been a 20 patch series, things would have been different
because sending a v2 for one typo means you are sending 20 emails in
other maintainers mailbox)
- it's more efficient (you don't lose one hour waiting for me to
answer) to just send the v2 and a message telling us to discard the v1
:)

Cheers,
Benjamin
