Subject: [PATCH 5/9] omap3: pm: sr: replace get_opp with freq_to_opp
Date: Wed, 11 Nov 2009 23:45:17 -0600	[thread overview]
Message-ID: <1258004721-7315-6-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1258004721-7315-5-git-send-email-nm@ti.com>

SmartReflex implements a get_opp to search through the opp table,
replace it with the accessor function as it is a duplicate of
freq_to_opp
