From 7131c883f995df9288f70879e501016119d4d971 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Thu, 24 Mar 2022 18:12:14 -0700 Subject: [PATCH] kasan: drop addr check from describe_object_addr Patch series "kasan: report clean-ups and improvements". A number of clean-up patches for KASAN reporting code. Most are non-functional and only improve readability. This patch (of 22): describe_object_addr() used to be called with NULL addr in the early days of KASAN. This no longer happens, so drop the check.
