"Backport" of 441bf7332d55 ("staging: m57621-mmc: delete driver from the tree.") as well for older stable series still supported?

Hi Greg, Sasha, all,

Prompted by https://bugs.debian.org/986949 it looks that files with prolematic license are present in stable series in drivers/staging/mt7621-mmc/ prior to 441bf7332d55 ("staging: m57621-mmc: delete driver from the tree.") where those were removed in 5.2-rc1.

As the license text at it is presented is problematic at best, would this removal make sense as well in the current other stable series which contain it? The files goes back to it's addition in 4.17-rc1.

So it would remain v4.19.y where the files should/can be removed as well from the staging area?

Regards, Salvatore
