R: [PATCH v2] gpiolib: Disallow identical line names in the same chip

Just a question: why "inside one chip" only?
The name should be unique for all gpiochips, since "gpiofind"
stops at the first name match, and doesn't show other gpios
names, even if they exist, with the same name, in other gpiochip.

I think that a rule as:

- names must be unique (avoid duplicates in any gpiochips)
