Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: ctxfi: Fix missing SPDIFI1 index handling
SPDIF1 DAIO type isn't properly handled in daio_device_index() for
hw20k2, and it returned -EINVAL, which ended up with the out-of-bounds
array access. Follow the hw20k1 pattern and return the proper index
for this type, too.
