Yikes. Missed that. In my build this is a warning which I overlooked. Is there some Kconfig to make it an ERROR like above? You applied the first patch so should I resubmit all other patches?

Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops") it is possible to initiate a device coredump from user-space. This patch adds support for it adding the .coredump() driver callback. As there is no longer a need to initiate it through debugfs remove that code.
