Subject: clk: rockchip: Checking a kmemdup() call in
 rockchip_clk_register_pll()

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “rockchip_clk_register_pll” contains also a call
of the function “kmemdup”.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/clk/rockchip/clk-pll.c?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n913
https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/clk/rockchip/clk-pll.c#L913

* Do you find the usage of the format string “%s: could not allocate
  rate table for %s\n” still appropriate at this place?

* Is there a need to adjust the error handling here?

Regards,
Markus
