PATCH 1/1 drm: Fix compilation failure

From: Sean Paul <[email protected]>

We had competing reverts/disable commits go in that caused issues with each other.

Christian committed 783195ec1cad ("drm/syncobj: disable the timeline UAPI for now v2"), which moved the CREATE_TYPE_TIMELINE #define internally and added a check in drm_syncobj.c. When Eric reverted the entire timeline patch, he cleaned up the #define in the new location, but failed to remove the check, causing the boom.

The error:

../drivers/gpu/drm/drm_syncobj.c: In function ‘drm_syncobj_create’:
../drivers/gpu/drm/drm_syncobj.c:281:14: error: ‘DRM_SYNCOBJ_CREATE_TYPE_TIMELINE’ undeclared (first use in this function); did you mean ‘DRM_SYNCOBJ_CREATE_SIGNALED’?
if (flags & DRM_SYNCOBJ_CREATE_TYPE_TIMELINE)

              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              DRM_SYNCOBJ_CREATE_SIGNALED

../drivers/gpu/drm/drm_syncobj.c:281:14: note: each undeclared identifier is reported only once for each function it appears in

Fixes 131280a162e7 ("drm: Revert syncobj timeline changes.")
