Subject: [RFC/PATCH 3/4] clk: Use lockless functions for debug printing
Date: Fri, 25 Apr 2014 15:44:47 -0700 [thread overview]
Message-ID: <1398465888-12610-4-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1398465888-12610-1-git-send-email-sboyd@codeaurora.org>
In the near future we're going to move the prepare lock to a
per-clock ww_mutex. Use the lockless functions here for printing
the rate and accuracy so that we don't run into AA deadlocks in
the future.
