[PATCH v3] lib/dynamic_debug: make better dynamic log output

From: Huang Shijie
Date: Tue Dec 10 2019 - 22:18:20 EST


The driver strings, device name and net device name are not changed for
the driver's dynamic log output. But dynamic_emit_prefix() which contains
the function names may change when the function names are changed.

So the patch makes the better dynamic log output.
