Subject: [PATCH 3.16 133/233] HID: microsoft: Add quirk for MS Surface
 Type/Touch cover

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Reyad Attiyat <reyad.attiyat@...il.com>

commit c5b2b809cee8db018ac68566fe2114c175d79b5b upstream.

The newer firmware on MS Surface 2 tablets causes the type and touch cover keyboards to timeout when waiting for reports.
The quirk HID_QUIRK_NO_INIT_REPORTS allows them to function normally.
