4.1-stable review patch. If anyone has any objections, please let me know.

commit f4745a92781b872455f32feb01d1dce92aefcb6c upstream.
Static analysis by cppcheck found an issue that was recently introduced by commit 471f7707b6f0b1 ("PM / clock_ops: make __pm_clk_enable more generic") where a return status in ret was not being initialised and garbage being returned when ce->status >= PCE_STATUS_ERROR.
The fact that ret is not being checked by the caller and that ret is only used internally __pm_clk_enable() to check if clk_enable() was OK means we can ignore returning it instead turn __pm_clk_enable() into function with a void return.
