From cad1c0dfc8961abeb92e5afbfa275b6122501e5f Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Fri, 12 Dec 2014 01:56:04 +0200 Subject: [PATCH] sh/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.
