Please specify the exact files that are being removed from sysfs, nobody
is going to understand what they're losing unless they look at the code.

OK, I'll figure out proper wording and resubmit tomorrow.

From: Michal Nazarewicz <mina86@mina86.com>
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”. This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.
This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures. All
of those represent the *maximal* speed given entity supports.
After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
supports, and
* usb_composite_driver::max_speed - maximal speed composite
gadget supports.

From: Michal Nazarewicz <mina86@mina86.com>
This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED
Kconfig options. Since now kernel allows many UDC drivers to be
compiled, those options may turn to no longer be valid. For
instance, if someone decides to build UDC that supports super
speed and UDC that supports high speed only, the latter will be
"assumed" to support super speed since USB_GADGET_SUPERSPEED will
be selected by the former.
The test of whether CONFIG_USB_GADGET_*SPEED was defined was just
an optimisation which removed otherwise dead code (ie. if UDC is
not dual speed, there is no need to handle cases that can happen
if speed is high). This commit removes those checks.

Did you compile-test the various intermediate stages (i.e., after the
first patch and after the second patch)? I bet not, because the change
to file_storage.c in 3/3 belongs in 2/3.

Sorry and thanks for catching that. I'll send the updated version by the
end of US/Pacific day in case someone else has some more comments.
