xorg-x11-server/u_CloseConsole-Don-t-report-FatalError-when-shutting-down.patch
Egbert Eich ebc18c5647 - Fix crash in abnormal condition (bnc#879666, bnc#879489):
* u_connection-avoid-crash-when-CloseWellKnownConnections-gets-called-twice.patch
    Fix a crash when CloseWellKnownConnections() gets called twice.
    This can happen if FatalError() is called in the shutdown procedure.
  * u_CloseConsole-Don-t-report-FatalError-when-shutting-down.patch
    Don't call FatalError() on errors in console ioctls when in shutdown.

Subject: [PATCH]CloseConsole: Don't report FatalError() when shutting down
Patch-mainline: to be upstreamed
Git-commit: 4edf1fd15b9d2746f1f83165ab45efbe35af8de8
Git-repo:
References: bnc#879666, bnc#879489

When encountering a problem while closing the console, don't report this
as a FatalError(). FatalError() will terminate the Xserver - no use calling
it when terminating anyway. Since FatalError() will call CloseConsole()
we would only come here again.
