From 777b25a2fea7129222eb11fba55c0a67982383ff Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 10 Oct 2005 21:24:20 -0700 Subject: [CCID]: Check if ccid is NULL in the hc_[tr]x_exit functions For consistency with ccid_exit and to fix a bug when IP_DCCP_UNLOAD_HACK is enabled as the control sock is not associated to any CCID.
