From c5ec5e1f7f33a18ea81d3d9254c5b49bbdfd5e16 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 18 Jul 2016 18:32:48 +0200 Subject: oxnas: revert to kernel 4.1 A bug resulting in the NAND not being detected by newer kernels has kept me sleepless for months and yet I wasn't able to discover the cause. Bring back patches and files for 4.1 until this has been resolved.
