From a9830fc388817c90282925694474fae005fec990 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 14 Dec 2020 19:21:38 +0200 Subject: catpt: Switch to use list_entry_is_head() helper Since we got list_entry_is_head() helper in the generic header, we may switch catpt to use it. It removes the need in additional variable.
