ALEGoToDefinition, how to go back to the function call?

[ubaldot]

Hello!
Say that I am working on file1.c that contains a call to a function foo for which I want to see its definition.
All I have to do is to place the cursor over the function call foo and run :ALEGoToDefinition. Perfect.
But then, after I looked the foo definition, I want to go back to my initial point, namely I want to go back to file1.c with the cursor placed on the function call foo.
How to do that?

Normally I use "ctrl-o". See :h ctrl-o or better :h jump-motions for more details.
