Subject: [PATCH 3/3] staging: rtl8188eu: remove core/rtw_debug.c
Remove core/rtw_debug.c and its associated definitions in
include/rtw_debug.h, as well as modifying the makefile. This file's
functions may have been intended to be hooked up in procfs, but as
they are unused, they are dead code and better to remove.
Signed-off-by: Phillip Potter <phil@...lpotter.co.uk>
