From 2f3b07a7fcaac760cfefec6af123d52b2ea7c71e Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Sun, 28 Jul 2013 11:21:58 +0900 Subject: [PATCH] mtd: nandsim: remove unused ns->geom.oobshift ns->geom.oobshift holds bits number in OOB size, but OOB size is not always power of two. So it is useless and it actually isn't used in this driver except for just printing the value at module loading.
