HID: Support Jess/Saitek Color Rumble Pad
Add support for another gamepad to the hid-pl driver. The "color rumble pad P580" marketed using the "Saitek" brand in Germany, and using a USB Vendor ID attributed to "Jess" seems to be electronically identical to the 4-field variant of the "Green Asia" gamepad. The pad has been tested to support rumble strengths up to 255, not just 127. Signed-off-by: Michael Karcher <kernel@mkarcher.dialup.fu-berlin.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
