Subject: [PATCH v2 09/12] pm: at91: rename function name: at91_slow_clock()-->at91_pm_suspend_sram_fn
Date: Mon, 26 Jan 2015 17:43:31 +0800	[thread overview]
Message-ID: <1422265411-23309-1-git-send-email-wenyou.yang@atmel.com> (raw)
In-Reply-To: <1422265005-22937-1-git-send-email-wenyou.yang@atmel.com>

As the file name's renaming, rename the file name at91_slow_clock()-->
at91_pm_suspend_sram_fn, rename the function handler's name at the same time.
