From a69f8d70d4979e482214d9604ab4223dc3a00ed6 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Sun, 14 Feb 2021 15:17:44 +0100 Subject: ptrlist: use ptr_list_nth() instead of linearize_ptr_list() Sparse has a few extra checkers for some functions. The one for memset has its own helper to retrieve its 3rd arguments. Remove this helper and use the generic ptr_list_nth() instead.
