H A Dclk-dra7-atl.cdiff 20411dad Mon Aug 18 10:56:55 MDT 2014 Nishanth Menon <nm@ti.com> clk: ti: dra7-atl: Provide error check for incoming parameters in set_rate

Check for valid parameters in check rate. Else, we end up getting
errors.

This occurs as part of the inital clock tree update of child clock
nodes where new_rate could be 0 for non functional clocks.

H A Dtrace_functions_graph.cdiff 1fe4293f Wed Jan 31 08:48:49 MST 2018 Changbin Du <changbin.du@intel.com> tracing: Fix missing return symbol in function_graph output

The function_graph tracer does not show the interrupt return marker for the
leaf entry. On leaf entries, we see an unbalanced interrupt marker (the
interrupt was entered, but nevern left).
