Subject: [PATCH 4.9 20/24] Revert "cifs: In Kconfig CONFIG_CIFS_POSIX needs depends on legacy (insecure cifs)"

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

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

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit 4cd376638c893cf5bf1072eeaac884f62b7ac71e which is
commit 6e785302dad32228819d8066e5376acd15d0e6ba upstream.

Yi writes:
	I notice that 4.4.169 merged 60da90b224ba7 ("cifs: In Kconfig
	CONFIG_CIFS_POSIX needs depends on legacy (insecure cifs)") add
	a Kconfig dependency CIFS_ALLOW_INSECURE_LEGACY, which was not
	defined in 4.4 stable, so after this patch we are not able to
	enable CIFS_POSIX anymore. Linux 4.4 stable didn't merge the
	legacy dialects codes, so do we really need this patch for 4.4?

So revert this patch in 4.9 as well.
