The patch titled
Subject: drivers/char/mem.c: simplify DEVPORT configuration
has been removed from the -mm tree. Its filename was
drivers-char-mem-simplify-devport-configuration.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rob Ward <robert.ward114@xxxxxxxxxxxxxx>
Subject: drivers/char/mem.c: 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.
