One memory leak fix on the atmel UDC. Several fixes for dwc2. A fix on composite.c to use usb_ep_free_request() when freeing struct usb_request. -----BEGIN PGP SIGNATURE----- iQJRBAABCAA7FiEElLzh7wn96CXwjh2IzL64meEamQYFAlh8p+gdHGZlbGlwZS5i YWxiaUBsaW51eC5pbnRlbC5jb20ACgkQzL64meEamQYhyRAAyLkOdd96m0pMmyJd TPRqlu/vPy2C39pb/9zLAxfZN7W6zYBzGMAR4xkh269j7Xp2JJwqi1Km/XgpCm2m nKO5Ras+CQN1ftg6aazawvwNMWPfUkqKmbkWQXk+64/gUNfCKEgB+BUZhdnY+siE rmzZ3zWhyutpF8KIbtKVMkuEXm9HVbBZxlkOIPTRyN4jGzPC3Rh0VLf4LrSSrnQN sc347xXOenOgxQvt6nUOtdtO8cdRaLco0bciAXB8AAhHIYHK1XaAGc9lmCPenFYq j+uANJ1QFdCaCgoqiQp7jLNWXScieFsdfCyoAZEJfro8PrKA5tjOGKHyUFuWTolz TuclbIHeFWqjqlYhV908HzzU6vTk0wK+5XAYVyaqaHp3jDtcL+2plBKEdFALvsxS QM/mj4nFcbdWNdukBFIDju/wGDo0syiNbZl5ss5VsJ/fW3kl8lu/iDsgRDalABj5 RUxVLIv+tkhiFkTS0Ah/Yf1UOejCREbd182z5LVz/Cyi3wOQwjtIPuSNoOF/GAj+ 3DfFUsljzhWfMbd65Agr4AipcZs5CmLKFQziE5tHR8HIL1ZRIivKnUdLNwOaFdOy 876oBV093dlnGfDbjCl1nkBjPPV/i481OIeZjmMegfmON/DyTNy/4BlvwpdedGkT 6KllpibySJa27BLrlgYA/0wrNCo= =yyt7 -----END PGP SIGNATURE----- Merge tag 'fixes-for-v4.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.10-rc5 One memory leak fix on the atmel UDC.

To understand all the Linux-USB framework, you'll use these resources:
* This source code. This is necessarily an evolving work, and
includes kerneldoc that should help you get a current overview.
("make pdfdocs", and then look at "usb.pdf" for host side and
"gadget.pdf" for peripheral side.) Also, Documentation/usb has
more information.
* The USB 2.0 specification (from www.usb.org), with supplements
such as those for USB OTG and the various device classes.
The USB specification has a good overview chapter, and USB
peripherals conform to the widely known "Chapter 9".
* Chip specifications for USB controllers. Examples include
host controllers (on PCs, servers, and more); peripheral
controllers (in devices with Linux firmware, like printers or
cell phones); and hard-wired peripherals like Ethernet adapters.
* Specifications for other protocols implemented by USB peripheral
functions. Some are vendor-specific; others are vendor-neutral
but just standardized outside of the www.usb.org team.
Here is a list of what each subdirectory here is, and what is contained in
them.
core/ - This is for the core USB host code, including the
usbfs files and the hub class driver ("hub_wq").
host/ - This is for USB host controller drivers. This
includes UHCI, OHCI, EHCI, and others that might
be used with more specialized "embedded" systems.
gadget/ - This is for USB peripheral controller drivers and
the various gadget drivers which talk to them.
Individual USB driver directories. A new driver should be added to the
first subdirectory in the list below that it fits into.
image/ - This is for still image drivers, like scanners or
digital cameras.
../input/ - This is for any driver that uses the input subsystem,
like keyboard, mice, touchscreens, tablets, etc.
../media/ - This is for multimedia drivers, like video cameras,
radios, and any other drivers that talk to the v4l
subsystem.
../net/ - This is for network drivers.
serial/ - This is for USB to serial drivers.
storage/ - This is for USB mass-storage drivers.
class/ - This is for all USB device drivers that do not fit
into any of the above categories, and work for a range
of USB Class specified devices.
misc/ - This is for all USB device drivers that do not fit
into any of the above categories.
