[PATCH 0/7] HID: revert the Logitech High Resolution wheel support

From: Benjamin Tissoires
Date: Wed Nov 21 2018 - 10:27:26 EST


It turns out that the implementation of the high resolution support of
Logitech wheels is rather incompatible with the mice from Microsoft.

We had a lengthy discussion off-list and the summary is quoted in 7/7.

The TL;DR, we need to revert the current series before it gets out in
a released kernel and work on a better approach for 4.21.

This patch series has informally been acked by Dmitry, Harry, Jiri, Nestor
and Peter, but I wouldn't mind a public ack before I push this to
the for-linus branch.

Dmitry, I chose to also revert "Input: Add the `REL_WHEEL_HI_RES` event code"
as the documentation needs to be updated.
I would understand if you rather keep the patch that way and we just update
the doc. This would help synchronizing the trees. So please tell me if you
want 7/7 in the series or not (I'll reshuffle the commit message to have
the summary from Peter).

Cheers,
Benjamin
