X-Git-Tag: v7.2-rc1~141^2~26^2~157
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=dc2d30e7db8321a6696d266838f7af7e9d1c7155;p=thirdparty%2Flinux.git

drm/doc: document DRM_IOCTL_SYNCOBJ_EVENTFD

struct drm_syncobj_eventfd was documented, but
DRM_IOCTL_SYNCOBJ_EVENTFD was not. This prevents references to this
define from being properly linkified in docs.
