From fb0a84e6de1b6bee0a0649cc7ed768f9ff2496bb Mon Sep 17 00:00:00 2001 From: Arthur Grillo Date: Fri, 1 Sep 2023 15:52:56 -0300 Subject: drm/tests: Zero initialize fourccs_out MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit fourccs_out array is not initialized. As the drm_fb_build_fourcc_list() doesn't necessarily change all the array, and the test compares all of it, the comparison could fail if the array is not initialized. Zero initialize the array to fix this.
