Most of these look fine, but...

...that (and the one in the subsequent context lines) looks horrible.
I'd suggest breaking after the opening parenthesis of the function call
and just indenting the arguments by one tab:
	foo_with_long_name(
		long_arg,
		another_long_arg);

Better yet, ignore checkpatch and format that call more readably as
though the 80 column rule didn't exist.
