            Bug ID: 96574
           Summary: cannot compile the driver: xf86InitFBManager undefined
           Product: xorg
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/openchrome
          Assignee: openchrome-devel at lists.freedesktop.org
          Reporter: bensberg at justemail.net

To prevent warnings passing by unnoticed, I compile with -Werror in my CFLAGS. 
Since some time this results in the following failure:

make[4]: Entering directory '/home/ben/Sources/openchrome/src'
/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..

via_ums.c: In function ‘umsCreate’:

[-Werror=implicit-function-declaration]
     ret = xf86InitFBManager(pScreen, &AvailFBArea);
           ^~~~~~~~~~~~~~~~~
via_ums.c:756:9: error: implicit declaration of function
‘xf86InitFBManagerLinear’ [-Werror=implicit-function-declaration]
         xf86InitFBManagerLinear(pScreen, offset, size);
         ^~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Makefile:593: recipe for target 'via_ums.lo' failed
make[4]: *** [via_ums.lo] Error 1

It seems that some header file, in which xf86InitFBManager() and
xf86InitFBManagerLinear() are defined, has gone missing or are mistakenly not
included.  But I have no idea where to look for the definition of these
functions.  Googling doesn't make me any the wiser.
