+Subject: [PATCH xserver] xfree86: Take the input lock for xf86RecolorCursor
+
+xf86RecolorCursor() may be called directly from XRecolorCursor as well
+as from xf86ScreenSetCursor(). In the latter case, the input lock is
+already held, but not for the former and so we need to add a wrapper
+function that acquires the input lock before performing
+xf86RecolorCursor()
+
