Subject: [PATCH] ARM: mvebu: compile pm code conditionally
Date: Mon, 20 Jun 2016 18:08:22 +0200 [thread overview]
Message-ID: <20160620160931.2714557-1-arnd@arndb.de> (raw)
A cleanup to include the headers correctly caused another build problem:
arch/arm/mach-mvebu/kirkwood-pm.c:70:13: error: redefinition of 'kirkwood_pm_init'
arch/arm/mach-mvebu/kirkwood-pm.h:23:20: note: previous definition of 'kirkwood_pm_init' was here
The underlying issue is that kirkwood-pm.o is not actually meant to be
used when CONFIG_PM is disabled, so we should also leave it out of the
Makefile.
The same seems to be true for the PM code in MACH_MVEBU_V7, and I'm
treating it the same way here.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fixes: d705c1a66e15 ("ARM: Kirkwood: fix kirkwood_pm_init() declaration/type")
