From 3a4bc2fb80fb1fc943b640aae87dc078ba2aad78 Mon Sep 17 00:00:00 2001 From: Rob Ward Date: Sun, 7 Dec 2014 15:40:35 +0000 Subject: drivers: char: mem: Simplify DEVPORT configuration Simplify the use of CONFIG_DEVPORT by making the port_fops so that it includes __maybe_unused. This enabled the multiple #ifdef's used for this structure to be removed and brings it in line with the use of CONFIG_DEVMEM This change should introduce no functional changes.
