Colin Ian King 9b50c185d2 drm/radeon: fix copy of uninitialized variable back to userspace ... commit 8dbc2ccac5 upstream. Currently the ioctl command RADEON_INFO_SI_BACKEND_ENABLED_MASK can copy back uninitialised data in value_tmp that pointer *value points to. This can occur when rdev->family is less than CHIP_BONAIRE and less than CHIP_TAHITI. Fix this by adding in a missing -EINVAL so that no invalid value is copied back to userspace.
