From 7e5385dc722258c862f969ab7e67907156ad0e3f Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 15 Mar 2016 17:34:56 +0100 Subject: clk: rockchip: drop old_rate calculation on pll rate changes Previously when everything happened in the set_rate callbacks itself we needed the old_rate value for the possible rate rollback, so that made it easy to also use it in the debug output. Now with the param-handling being done in separate functions, reading and recalculating the current pll rate only to use it in a debug message that won't get displayed in regular cases anyway is quite a waste. Therefore drop that value from the debug output. In the worst case that previous rate will have been displayed on the rate change before.
