Subject: [PATCH 3.12 021/206] HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB Keykoard

From: Jiri Kosina <jkosina@...e.cz>

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

===============

commit 9ea63c439c5dffcb7c46c741929fe74b31b9676b upstream.

The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID
1a2c:0023 does not seem to be handling the reports initialization very well.
This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel
when connected, and a delay before its initialization.  This patch adds the
quirk for this device, which causes the delay to disappear.

[jkosina@...e.cz: remove superfluous comment and fix ordering]
