Subject: blackfin/uaccess: fix sparse errors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f5e0c47ef3293bef8eab634e5849c2559ed48a39;p=linux-beck.git

blackfin/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.
