[048/101] HID: usbhid: Add support for SiGma Micro chip

From: Greg KH

2.6.33-longterm review patch. If anyone has any objections, please let us know.

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

From: Jeremiah Matthey <sprg86@xxxxxxxxx>

commit f5e4282586dc0c9dab8c7d32e6c43aa07f68586b upstream.

Patch to add SiGma Micro-based keyboards (1c4f:0002) to hid-quirks.

These keyboards dont seem to allow the records to be initialized, and hence a
timeout occurs when the usbhid driver attempts to initialize them. The patch
just adds the signature for these keyboards to the hid-quirks list with the
setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the
timeout to occur.
