Subject: [PATCH 3.12 054/124] usbhid/quirks: Ignore Riso Kagaku Webmail Notifier

From: Christian Vogel <vogelchr@...el.cx>

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

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

commit 759db9ead2c064203e9cb46bfff7c8ef25417b65 upstream.

The "Webmail Notifier" is a USB controlled LED that appears as a HID
device. When trying to change the LED via hidraw it returns malformed
reports. As "usbled" supports it, we blacklist it in usbhid.
