I don't think there is any disagreement nor that there are any conflicting
viewpoints. As explained in previous e-mails it is unlikely that anyone is
using these kernel drivers and as far as I know Linus is OK with removing
unused kernel drivers.

Removing a kernel driver is not a nuclear option. You may not be aware of
this but it happens all the time. From a maintainer point of view it is a
very sensible action because there are people who keep submitting cleanup
patches for kernel drivers they do not use themselves. Every individual
patch needs some attention and hence causes some work for a kernel
maintainer. Removing kernel drivers that are not used helps to reduce the
workload of a maintainer and hence is a rational action. Additionally, if
anyone would ever complain about removal of a kernel driver, it can be
brought back by reverting the commit through which it has been removed.
Martin, please reply if you see this differently.
