Subject[PATCH RESEND] kunit: string-stream: Allow ERR_PTR to be passed to string_stream_destroy()
Date
Check the stream pointer passed to string_stream_destroy() for
IS_ERR_OR_NULL() instead of only NULL.

Whatever alloc_string_stream() returns should be safe to pass
to string_stream_destroy(), and that will be an ERR_PTR.

It's obviously good practise and generally helpful to also check
for NULL pointers so that client cleanup code can call
string_stream_destroy() unconditionally - which could include
pointers that have never been set to anything and so are NULL.
