From 5ed22cebbacc3d434fe4df5e7178cb2b79042d41 Mon Sep 17 00:00:00 2001 From: Frank Haverkamp Date: Wed, 29 Jun 2016 15:47:43 +0200 Subject: [PATCH] GenWQE: Change default access rights for device node Since it should always be ok for normal users to operate the accelerator, it makes sense to change it in our driver, rather than adding udev rules for all Linux distributions.
