Subject: [PATCH] xtensa: fix kconfig unmet dependency warning for HAVE_FUTEX_CMPXCHG
Date: Wed, 26 May 2021 00:03:37 -0700	[thread overview]
Message-ID: <20210526070337.28130-1-rdunlap@infradead.org> (raw)

XTENSA should only select HAVE_FUTEX_CMPXCHG when FUTEX is
set/enabled. This prevents a kconfig warning.

WARNING: unmet direct dependencies detected for HAVE_FUTEX_CMPXCHG
  Depends on [n]: FUTEX [=n]
  Selected by [y]:
  - XTENSA [=y] && !MMU [=n]

Fixes: d951ba21b959 ("xtensa: nommu: select HAVE_FUTEX_CMPXCHG")
