From mboxrd@z Thu Jan 1 00:00:00 1970 From: linux@arm.linux.org.uk (Russell King - ARM Linux) Date: Wed, 22 Jun 2011 16:15:37 +0100 Subject: [PATCH 21/25] ARM: pm: samsung: no need to call flush_cache_all() In-Reply-To: <20110622150816.GT23234@n2100.arm.linux.org.uk> References: <20110622150816.GT23234@n2100.arm.linux.org.uk> Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The core suspend code calls flush_cache_all() immediately prior to calling the suspend finisher function, so remove these needless calls from the finisher functions.
