A couple more modifications to the declarations tests.
o Declarations can also be bitfields so exclude things with a colon
o Make sure the current and previous lines are indented the same
to avoid matching some macro where a struct type is passed on
the previous line like:
next = list_entry(buffer->entry.next,
struct binder_buffer, entry);
if (buffer_start_page(next) == buffer_end_page(buffer))
