[PATCH] drivers: tty: serial: Add missing of_node_put() in serial-tegra.c

[PATCH] drivers: tty: serial: Add missing of_node_put() in serial-tegra.c

[heliang]

In tegra_uart_init(), of_find_matching_node() will return a node
pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.

How do we enforce that? What if Wong, Adele or Beyonce submit a patch?

What happens if that patch gets reposted, with S-o-b: He Liang
<windhl@126.com> or Hel Iang, Heli Ang? Do you know any of those are
real names? What happens if they post a real name in
Mandarin/Thai/Cyrillic, can you validate it?

Really we require you have an identity attached to an email. If there
is a problem in the future, we'd prefer the email continues to work so
that you are contactable. If you are submitting a small amount of
changes it's probably never going to matter. If you are submitting
larger bodies of work of course it would be good to have a company or
larger org attached to track things down legally later, but again that
isn't always possible.

I don't think alienating the numerous developers who no longer use
their legal names are identified by one name, but haven't changed
their legal one yet people who get married and change their legal name
but don't change their contribution name and I could run this sentence
on forever.

Yeah like absolute best case trying to "enforce" this just results in
encouraging people to come up with entirely fake but English looking
names for themselves. Which ... just no.

Agree, again, I'd prefer to take real names in native languages, our
tools can handle that just fine.  No need to make up anything.

hi, Greg K-H, 

I have resent a new patch for my commit of tegra_uart_init() bug with my real name for Sob.

So there is anyother thing I should do?

Since this is the only mail from this chain in my inbox and I asked the
same question as Greg on other patches:
I think it is pretty reasonable to /ask/ if something is not a real name
when you see something like "heliang <windhl@126.com>" where there's a
clear difference. And "It is my real name" is a perfectly reasonable
response /shrug.
Trust but verify right? It's not like I'm gonna argue the toss with
someone if they say it is their real name...

Thanks,
Conchubhar ;)

Sorry, Conor and Grep K-H.

I did not explain clearly and I respect all your suggestions.

I have resent with 'Liang He' as my real name for all patches which I sent with heliang yesterday.
And I use '[PATCH v2]' for there resent patches.

Sorry again.

As per our rules in the kernel, we can not accept a signed-off-by by a
known anonymous person.  When you can obviously see that the name is
incorrect (as has happened recently with different names being used for
the from: and the s-o-b lines in the email address), you have to ask for
clarification.  It's something that all maintainers should be doing.

I would love for people to use their names in their native language,
there's no need to make up english-sounding names at all.  We have many
examples of this in commits already, I would be happy if we get more.

And yes, validating names in those languages is usually not very
difficult.
