[PATCH 0/8] USB: fix up some old and obsolete terminology, we can do better

[Greg Kroah-Hartman]

There are a number of places in the USB kernel code where terms that are
"loaded" are used.  Fix this up to be more specific and inclusive as
there is no need for us to use these terms at all.

In one case, this ends up saving code, a nice side affect.

[PATCH 1/8] USB: rename USB quirk to USB_QUIRK_ENDPOINT_IGNORE

[Greg Kroah-Hartman]

The USB core has a quirk flag to ignore specific endpoints, so rename it
to be more obvious what this quirk does.

A note for future reference, not sure what you mean with driver
API here. If you mean the in kernel API, the kernel rules are
that we are always free to change that (Linux does not have a
stable driver API).

So if a header does not sit under include/uapi (indicating that
it is an userspace API) then a change like this is fine.

Regards,

Hans

I meant the internal driver API, which might break out-of-tree drivers.
I know that this API is fluid, and that there are no stability
guarantees, but I'd still expect at least a note in the commit message
to that effect.

There is no such thing.  Well, there might be, but we don't care and
have to act as if there are no such thing otherwise we would never be
able to change anything :)

Why?  Who cares?  Anyone who lives outside of the kernel already knows
they have to dig in the kernel if their code breaks, that's the cost of
living outside of the kernel.

[PATCH 2/8] USB: rename USB OTG hub configuration option

The USB OTG code has the ability to disable external hubs, but the
configuration option for it is oddly named.  Rename it to be more

[PATCH 8/8] USB: OTG: rename product list of devices

[Greg Kroah-Hartman]

Rename the list of specific devices that an OTG device could support to
make it more obvious as to what this list is for and what it is doing.
Also rename the configuration option to make it more obvious as well.
