Right, this is all less then ideak, but I believe that this is the
best we can do for now.

Are you happy with the platform_data for this driver as defined in
patch 4/12 ? :

https://lore.kernel.org/platform-driver-x86/20211008162121.6628-1-hdegoede@xxxxxxxxxx/T/#m745cc1191f531a57ae7998f5c8817ba9a46f0fed

And are you ok with me doing an immutable-branch based on
5.15-rc1 with just the patch adding the platform_data
in there ?  The platform_data is used/shared by most patches
in this series. So the idea is to have an immutable branch
which can be shared/merged by all subsystems which have
patches in this patch series.

Hans
