From 458e3192455547bb4dce27e060c24cc22a2bd87d Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 27 Jan 2015 17:20:10 +0100 Subject: [PATCH] CRIS: uaccess: fix sparse errors virtio wants to read bitwise types from userspace using get_user. At the moment this triggers sparse errors, since the value is passed through an integer. Fix that up using __force. Signed-off-by: Michael S.
