From dbb28ef5cf5318b0abb95712f1cfafaa032796e5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20Bie=C3=9Fmann?= Date: Fri, 31 Aug 2012 13:35:42 +0200 Subject: [PATCH] mtd: omap2: fix module loading MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 4d3d688da8e7016f15483e9319b41311e1db9515 upstream. Unloading the omap2 nand driver missed to release the memory region which will result in not being able to request it again if one want to load the driver later on. This patch fixes following error when loading omap2 module after unloading: ---8<--- ~ $ rmmod omap2 ~ $ modprobe omap2 [ 37.420928] omap2-nand: probe of omap2-nand.0 failed with error -16 ~ $ --->8--- This error was introduced in 67ce04bf2746f8a1f8c2a104b313d20c63f68378 which was the first commit of this driver.
