Subject: [PATCH AUTOSEL 4.4 21/23] cifs: In Kconfig CONFIG_CIFS_POSIX needs depends on legacy (insecure cifs)

From: Steve French <stfrench@...rosoft.com>

[ Upstream commit 6e785302dad32228819d8066e5376acd15d0e6ba ]

Missing a dependency.  Shouldn't show cifs posix extensions
in Kconfig if CONFIG_CIFS_ALLOW_INSECURE_DIALECTS (ie SMB1
protocol) is disabled.
