Subject: [PATCH 09/10] OMAP: omap_device: fix nsec/usec conversion in latency calculations
Date: Thu, 03 Dec 2009 06:49:57 -0700 [thread overview]
Message-ID: <20091203134955.17146.60626.stgit@localhost.localdomain> (raw)
In-Reply-To: <20091203134852.17146.81997.stgit@localhost.localdomain>
From: Kevin Hilman <khilman@deeprootsystems.com>
Use
usecs = nsecs / NSEC_PER_USEC;
instead of
usecs = nsecs * NSEC_PER_USEC;
