From 907cd6de621def5dbfb89806ad58ff671c701682 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Delgado Date: Thu, 4 Oct 2018 15:01:04 +0200 Subject: [PATCH] mtd: maps: gpio-addr-flash: Fix ioremapped size We should only iomap the area of the chip that is memory mapped. Otherwise we could be mapping devices beyond the memory space or that belong to other devices.
