[d-kernel] [PATCH 3/4] wait: allow to use __wake_up_pollfree() from GPL modules

[lakostis@altlinux.org]

From: Andrea Righi <andrea.righi@canonical.com>

commit ebafbcf7f32d ("UBUNTU: SAUCE: binder: turn into module")
is changing binder to be a module, but __wake_up_pollfree() can only be
used internally by the kernel.

Make __wake_up_pollfree an EXPORT_SYMBOL_GPL so that it can be used by
the binder module.
