this variable is not used in the rest of this function, something's not
right here...

is this missing ret = -ENOMEM?

same here, ret = -ENOMEM; ?

or use what the existing code does for other links:

devm_err:
return -ENOMEM;

no longer necessary, and probably will not compile. please remove this
field.
