Hi Stefan, I'm validating if all drivers are behaving equally with respect to the error codes returned to userspace, and double-checking with the API.
On almost all places, -EFAULT code is used only to indicate when copy_from_user/copy_to_user fails. However, firedtv uses a lot of -EFAULT, where it seems to me that other error codes should be used instead (like -EIO for bus transfer errors and -EINVAL/-ERANGE for invalid/out of range parameters). I'll be posting soon a series of patches fixing the error codes on the other places, but, as I don't know how do you use -EFAULT inside the firewire core, I prefer to not touch at firedtv. Could you please take a look on it? Thanks!
