The variable capability is being assigned a value that is never
read and is being re-assigned later. The assignment is redundant and
can be removed. Also remove empty line before assignment to capability.

This part doesn't seem strictly related to the patch description.
But in looking at it more closely, I wonder if it would be good
to reduce the scope of capability to this context (and leave the bank
line).

In any case, I agree that this patch is correct, and I'm happy with
it with or without the change I suggested above.
