Subject: [PATCH 4.10 068/110] HID: multitouch: enable the Surface 4 Type Cover Pro (JP) to report multitouch data

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yuta Kobayashi <alu.ula@...look.com>

[ Upstream commit 4fed0231994b27b3896bc63885ac66d02fff625b ]

Since commit 8fe89ef076fa1 ("HID: multitouch: enable the Surface 3 Type
Cover to report multitouch data"), the TypeCover can be properly handled
by hid-multitouch and don't require any special quirk in the kernel.

Remove the support of the Surface 4 Type Cover Pro (JP) from
hid-microsoft so it can properly report multitouch from the touchpad.
