+Subject: [PATCH] clk: Always clamp the rounded rate
+
+The current core while setting the min and max rate properly in the
+clk_request structure will not make sure that the requested rate is
+within these boundaries, leaving it to each and every driver to make
+sure it is.
+
+Add a clamp call to make sure it's always done.
