Subject: autofs - make autofs4 Kconfig depend on AUTOFS_FS
Setting AUTOFS_FS and AUTOFS4_FS to y or m results in a compile failure.
It isn't possible to unset one if the other is set because it introduces a
circular dependency.
But adding "depends on AUTOFS_FS = n" will make autofs4 appear under the
autofs entry which should call attention to it. It also results in
AUTOFS4_FS being removed from .config for any setting of AUTOFS_FS except
n.
Adding a "NOTE" to the AUTOFS4_FS help text will hopefully raise awareness
of the change to smooth the transition.
