No, we don't want any possibility of output in the
CONFIG_DYNAMIC_DEBUG=n case. This is extra debug that only makes sense
in the CONFIG_DYNAMIC_DEBUG case.
No, that doesn't work the same.
Look at your conversion of drivers/acpi/nfit/core.c
dev_dbg outputs always when DEBUG is defined and
optionally outputs when CONFIG_DYNAMIC_DEBUG is enabled.
