Next message: Christophe Leroy: "[PATCH] powerpc: Add missing SPDX license identifiers to DTS files"
Previous message: Neil Armstrong: "Re: [PATCH] drm: bridge: it66121: Remove redundant check"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Several files are missing SPDX license identifiers.

Add to them the default kernel license identifier, ie GPL-2.0.

DTS files are handled in a separate commit.
