Subject: PM / clk: don't return int on __pm_clk_enable()

From: Colin Ian King <colin.king@canonical.com>

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.
