From 836d13a6ef8a2eb0eab2bd2de06f2deabc62b060 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Sun, 21 Jul 2024 16:36:18 +0300 Subject: [PATCH] xz: switch from public domain to BSD Zero Clause License (0BSD) Remove the public domain notices and add SPDX license identifiers. Change MODULE_LICENSE from "GPL" to "Dual BSD/GPL" because 0BSD should count as a BSD license variant here. The switch to 0BSD was done in the upstream XZ Embedded project because public domain has (real or perceived) legal issues in some jurisdictions.
