CVE-2026-31777

In the Linux kernel, the following vulnerability has been resolved:

ALSA: ctxfi: Check the error for index mapping

The ctxfi driver blindly assumed a proper value returned from
daio_device_index(), but it’s not always true. Add a proper error
check to deal with the error from the function.
