[PATCH net-next 6/7] net: ipa: kill ipa_power_modem_queue_active()

From: Alex Elder
Date: Tue Jan 30 2024 - 14:25:28 EST


All ipa_power_modem_queue_active() does now is call netif_wake_queue().
Just call netif_wake_queue() in the two places it's needed, and get
rid of ipa_power_modem_queue_active().
