MLOCK's debug info, spewed on CDMA timeout, contains meaningless MLOCK owner channel ID because HOST1X_SYNC_MLOCK_OWNER_CHID_F() returns shifted value, while unshifted should be used. Fix it by changing '_F' to '_V'. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-By: Terje Bergstrom <tbergstrom@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
