Subject: [PATCH v4 1/6] Replace ternary operator to macro
Date: Thu, 20 Feb 2014 20:23:40 +0400	[thread overview]
Message-ID: <1392913425-29369-2-git-send-email-a.perevalov@samsung.com> (raw)
In-Reply-To: <1392913425-29369-1-git-send-email-a.perevalov@samsung.com>

For extensibility purpose it's better to have _switch_ type mechanism
for representing human readable CLOCKID* and HRMODE.
