From 21457f4a91cb522f1a3ad9741ff1d25fadfaa3c5 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 31 Aug 2022 13:24:44 +0100 Subject: rxrpc: Remove rxrpc_get_reply_time() which is no longer used Remove rxrpc_get_reply_time() as that is no longer used now that the call issue time is used instead of the reply time.
