Maybe a patch from you to move it?
It seems pretty clean to me.
Are you going to keep all the _dbg statements?
You might add a Kconfig CONFIG_SEP_DEBUG block with a
Makefile entry of:
ccflags-$(CONFIG_SEP_DEBUG) := -DDEBUG
to specifically enable DEBUG without dynamic debug.
Here's a Kconfig typo fix and a suggestion to rename the
uses of dev_dbg and dev_warn to sep_<level> to make the
code a bit shorter and more compact.
