6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kelvin Cao <kelvin.cao@xxxxxxxxxxxxx> [ Upstream commit 0fb53e64705ae0fabd9593102e0f0e6812968802 ] Advertise support of Gen5 devices in the driver's device ID table and add the same IDs for the switchtec quirks. Also update driver code to accommodate them.
