Alan Coopersmith 7cc0695cf7 modesetting: avoid memory leak when ms_present_check_unflip() returns FALSE

      Memory leak of pointer event allocated with calloc(1, 16)
        at line 470 of hw/xfree86/drivers/modesetting/present.c in
	function 'ms_present_unflip'.
          event allocated at line 431 with calloc(1, 16)
          event leaks when ms_present_check_unflip(...) == 0 at line 438

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
