[PATCH 01/25] clk: Fix debugfs clk_possible_parents for clks without parent string names
From: Chen-Yu Tsai <wens@kernel.org>
Date: 2019-05-20 08:07:28
Also in:
linux-clk, lkml
Subsystem:
common clk framework, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Linus Torvalds
From: Chen-Yu Tsai <redacted>
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")
