From a500f3751d3c861be7e4463c933cf467240cca5d Mon Sep 17 00:00:00 2001 From: Brahmajit Das Date: Wed, 2 Oct 2024 14:53:11 +0530 Subject: [PATCH] drm/display: Fix building with GCC 15 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit GCC 15 enables -Werror=unterminated-string-initialization by default. This results in the following build error drivers/gpu/drm/display/drm_dp_dual_mode_helper.c: In function ‘is_hdmi_adaptor’: drivers/gpu/drm/display/drm_dp_dual_mode_helper.c:164:17: error: initializer-string for array of ‘char’ is too long [-Werror=unterminated-string-initialization] 164 | "DP-HDMI ADAPTOR\x04"; | ^~~~~~~~~~~~~~~~~~~~~ After discussion with Ville, the fix was to increase the size of dp_dual_mode_hdmi_id array by one, so that it can accommodate the NULL line character. This should let us build the kernel with GCC 15.
