Subject: [PATCH] wifi: mt76: mt7996: select CONFIG_RELAY

From: Arnd Bergmann <>

Without CONFIG_RELAY, the driver fails to link:

ERROR: modpost: "relay_flush" [drivers/net/wireless/mediatek/mt76/mt7996/mt7996e.ko] undefined!
ERROR: modpost: "relay_switch_subbuf" [drivers/net/wireless/mediatek/mt76/mt7996/mt7996e.ko] undefined!
ERROR: modpost: "relay_open" [drivers/net/wireless/mediatek/mt76/mt7996/mt7996e.ko] undefined!
ERROR: modpost: "relay_reset" [drivers/net/wireless/mediatek/mt76/mt7996/mt7996e.ko] undefined!
ERROR: modpost: "relay_file_operations" [drivers/net/wireless/mediatek/mt76/mt7996/mt7996e.ko] undefined!

The same change was done in mt7915 for the corresponding copy of the code.

Fixes: 98686cd21624 ("wifi: mt76: mt7996: add driver for MediaTek Wi-Fi 7 (802.11be) devices")
