From: Chen-Yu Tsai <[email protected]>
Following the commit fc0c209c147f ("clk: Allow parents to be specified
without string names"), the parent name string is not always populated.
Instead, fetch the parents clk_core struct using the appropriate helper,
and read its name directly.
Fixes: fc0c209c147f ("clk: Allow parents to be specified without string names")
