From bf3c44f67cdff428ca81a4542fc7891540a3cd23 Mon Sep 17 00:00:00 2001 From: Dragan Simic Date: Mon, 10 Jun 2024 07:21:12 +0200 Subject: [PATCH] kbuild: Install dtb files as 0644 in Makefile.dtbinst commit 9cc5f3bf63aa98bd7cc7ce8a8599077fde13283e upstream. The compiled dtb files aren't executable, so install them with 0644 as their permission mode, instead of defaulting to 0755 for the permission mode and installing them with the executable bits set. Some Linux distributions, including Debian, [1][2][3] already include fixes in their kernel package build recipes to change the dtb file permissions to 0644 in their kernel packages. These changes, when additionally propagated into the long-term kernel versions, will allow such distributions to remove their downstream fixes.
