Bug#986949: Linux 4.19 staging driver mt7621-mmc has problematic license
Source: linux
Version: 4.19.181-1
X-Debbugs-CC: jan.kiszka@siemens.com
During licensing checks of the "linux" sources, we identified
problematic files in drivers/staging/mt7621-mmc. As an example,
drivers/staging/mt7621-mmc states:
[...]
* This software/firmware and related documentation ("MediaTek
Software") are
* protected under relevant copyright laws. The information contained
herein
* is confidential and proprietary to MediaTek Inc. and/or its licensors.
[...]
This was also identified by Linux kernel maintainers and driver was
removed from later kernel versions, see
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=441bf7332d55c4d34afae9ffc3bbec621093f4d1.
However, it seems this commit was not picked by stable 4.19 tree (yet).
It doesn't seem those drivers are included in any Debian binary package
(they seem to depend on CONFIG_RALINK which I couldn't find in the
buster kernel configs), but it's still distributed by Debian as part of
http://deb.debian.org/debian/pool/main/l/linux/linux_4.19.181.orig.tar.xz.
The issue seems to only affect kernels prior to v5.2 and past v4.16,
thus practically only buster.
