No, that is not the way we indent. The alignment is relative to the open
parenthesis:

  foo(arg1,
      arg2);

Btw, if you run checkpatch --strict, you'll see it complaining if the
alignment is different:

	CHECK: Alignment should match open parenthesis
	#2: FILE: a.c:2:
	+void foo(int arg1,
	+		int arg2)

The alignment here is given by the first argument:

   bitfield = BIT_1 |
              BIT_2 |
              BIT_3 |
              ...

or

   bitfield = BIT_1
              | BIT_2
              | BIT_3
              ...

On media, we usually prefer the first form.
