Subject: [PATCH 3/7] ARM: OMAP2+: powerdomain: pwrdm_for_each_clkdm iterate only valid clkdms
Date: Fri, 22 Aug 2014 08:49:29 -0500 [thread overview]
Message-ID: <1408715373-25791-4-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1408715373-25791-1-git-send-email-nm@ti.com>
No need to invoke callback when the clkdm pointer is NULL.
