Subject[PATCH v2 0/3] Support multitouch touchpads in Surface TypeCover
Date
Hi,

this is mostly a resubmission of v1, with one patch exchanged.

The latest investigations by Dennis Chen showed that the first patch did
not changed the internal HID device quirk. So I think the first patch is
still valid for upstream.

Patch 2/3 "HID: multitouch: do not retrieve all reports for all devices" is
an attempt to pro-actively fix the other issues of the TypeCover. It looks
like the quirk HID_QUIRK_NO_INIT_REPORTS was dropped somewhere, but the quirks
set in hid-multitouch were kept. After further thoughts, I think we should
simply mimic the Windows driver and only retrieve the features we actually need.

With this patch, we don't need to add a special case for the Surface 3
cover, the default class just works.

Cheers,
Benjamin
