It's i2o, not io, and it is on the way out of the kernel.

#2 lore raw
Quoted 1 line · Julia Lawall

It's i2o, not io, and it is on the way out of the kernel.

sorry about that,
since it is on its way out I guess there is no need for me to submit a correct version of this patch?

Are there resources to know whether or not a driver will be dropped or is it enough to check if there is
a TODO file in its directory?

These are the staging drivers that I know of:
