From 4255a8e199a00faa29b84c47ad57427dd1412581 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 14 Dec 2014 18:53:10 +0200 Subject: [PATCH] xtensa/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.
