Does this actually need to be templatized? Looks like T& messages could just be
const PermissionMessages& messages?

[meacer, 2014/07/07 21:57:32]

Also, ContainBothMessages -> ContainsBothMessages 

[mhm, 2014/07/07 22:33:09]

No it doesn't. I just followed the SuppressMessage signature.

[mhm, 2014/07/07 22:33:09]

Done.

nit: I think it'll look better if you format this like the previous statement:

ContainsBothMessages(messages,
                     PermissionMessage::kUsb,
                     PermissionMessage::kSerial)) {    

[mhm, 2014/07/07 22:33:09]

This was done with auto formatting "git cl format". Sometime it messes things up
:-)

You might want to test this logic with multiple "usb" permissions too.
