The sed_ioctl() function is written to be compatible between 32-bit and 64-bit processes, however compat mode is only wired up for nvme, not for sd. Add the missing call to sed_ioctl() in sd_compat_ioctl(). Fixes: d80210f25ff0 ("sd: add support for TCG OPAL self encrypting disks") Cc: linux-scsi@vger.kernel.org Cc: "James E.J.
