Hi, I'm getting a checkpatch warning with the latest amdkfd-next branch (4.17-rc2) when adding a new file: WARNING: Missing or malformed SPDX-License-Identifier tag in line 1 #34: FILE: drivers/gpu/drm/amd/amdkfd/cwsr_trap_handler.h:1: I've read Documentation/process/license-rules.rst but I'm unsure what would be the correct license identifier to go with the license header we use in most of our source files. I think it would be one of these: Â Â Â Â Â // SPDX-License-Identifier: GPL-2.0 OR MIT Â Â Â Â Â // SPDX-License-Identifier: GPL-2.0 OR BSD-2-Clause Can someone confirm. Once that's clarified, we should probably add the appropriate license identifier to all our source files.
