BugLink: https://bugs.launchpad.net/bugs/2089340 [ Upstream commit 99c5c4c60e0db1d2ff58b8a61c93b6851146469f ] TDX is going to have more than one reason to fail enc_status_change_prepare(). Change the callback to return errno instead of assuming -EIO. Change enc_status_change_finish() too to keep the interface symmetric. Signed-off-by: Kirill A.
