[PATCH 4.14 102/109] Fix misannotated out-of-line _copy_to_user()

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe Leroy <christophe.leroy@xxxxxx>


[ Upstream commit a0e94598e6b6c0d1df6a5fa14eb7c767ca817a20 ]

Destination is a kernel pointer and source - a userland one
in _copy_from_user(); _copy_to_user() is the other way round.

Fixes: d597580d37377 ("generic ...copy_..._user primitives")
