From 0ff9bf9f3e0ce212aabea84365575466039e8c46 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 12 May 2021 21:30:51 +0100 Subject: [PATCH] drm: simpledrm: Fix use after free issues There are two occurrances where objects are being free'd via a put call and yet they are being referenced after this. Fix these by adding in the missing continue statement so that the put on the end of the loop is skipped over.
