  The device operation .dev_close was returning void.
This driver interface is changed to return an int.

Note that the API rte_eth_dev_close() is still returning void,
although a deprecation notice is pending to change it as well.

Why not update the 'rte_eth_dev_close()' in this patch? After the 
updates below it should be easier.

Yes it is a step in the right direction.
Changing the API means adding some error checks in every apps.
The reason for not doing is that I did not commit for this task,
and I am not the author of the deprecation notice.
We can discuss how to follow up once this series is merged.

Not sure what application can really do if dev_close fails other than call rte_exit()?

At least, it can show a message to the user.

Agree, but no code checks return from close() system call now.
At least testpmd should be updated; the examples are fine.

How do you explicitly silence the static code analyzers?
Do you recommend adding (void) in front of the call to close()?

Coverity usually gives something like, "return value of foo() is not checked
but checked 10 other places"

Yes so it should be silenced with (void) or ret =

Does coverity still give the warning if the majority of cases don't
actually check the return value?

As far as I know it does, so just assigning return value to a variable 
and not checking it at all will generate warnings.

It looks like coverity only looks at some functions and if majority is checking.
For example, it never nags about just calling close().
