5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dragan Simic <dsimic@xxxxxxxxxxx> 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.
