Subject: clk: samsung: Checking a kmemdup() call in _samsung_clk_register_pll()
Date: Sat, 12 Oct 2019 16:17:03 +0200
Message-ID: <c1bc5e4d-0802-4485-2c07-248bab2a3330@web.de> (raw)

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “_samsung_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/samsung/clk-pll.c?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n1275
https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/clk/samsung/clk-pll.c#L1275

* 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
