Subject: fbdev/cyber2000fb: Unexport symbols
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3bb0aeb60aa5c62870b51dcf9cf705b8339be24d;p=thirdparty%2Flinux.git

fbdev/cyber2000fb: Unexport symbols

Fix the compile-time warning

  drivers/video/fbdev/cyber2000fb.c: warning: EXPORT_SYMBOL() is used, but #include <linux/export.h> is missing

The affected symbols are not used anywhere, so remove the functions
entirely.

v2:
- remove unused functions (Helge)
