[PATCH] net: ena: Remove deadcode
Posted by linux@treblig.org 3 weeks ago 
From: "Dr. David Alan Gilbert" <linux@treblig.org>

ena_com_get_dev_basic_stats() has been unused since 2017's
commit d81db2405613 ("net/ena: refactor ena_get_stats64 to be atomic
context safe")

ena_com_get_offload_settings() has been unused since the original
commit of ENA back in 2016 in
commit 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic
Network Adapters (ENA)")

Remove them.
