Subject: drm/nouveau: Checking a kmemdup() call in
 nouveau_connector_of_detect()

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “nouveau_connector_of_detect” contains still
an unchecked call of the function “kmemdup”.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/nouveau/nouveau_connector.c?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n476
https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/gpu/drm/nouveau/nouveau_connector.c#L476

How do you think about to improve it?

Regards,
Markus
