Subject[PATCH] drm/amdkfd: make SPDX License expression more sound
Commit b5f57384805a ("drm/amdkfd: Add sysfs bitfields and enums to uAPI")
adds include/uapi/linux/kfd_sysfs.h with the "GPL-2.0 OR MIT WITH
Linux-syscall-note" SPDX-License expression.

The command ./scripts/ warns:

include/uapi/linux/kfd_sysfs.h: 1:48 Exception not valid for license MIT: Linux-syscall-note

For a uapi header, the file under GPLv2 License must be combined with the
Linux-syscall-note, but combining the MIT License with the
Linux-syscall-note makes no sense, as the note provides an exception for
GPL-licensed code, not for permissively licensed code.

So, reorganize the SPDX expression to only combine the note with the GPL
License condition. This makes spdxcheck happy again.

I am not a lawyer and I do not intend to modify the actual licensing of
this header file. So, I really would like to have an Ack from some AMD
developer here.

Maybe also a lawyer on the linux-spdx list can check my reasoning on the
licensing with the exception note?
