A few more fixes for v3.4-rc cycle. It includes a couple of fixes to the ordering of the methods in udc-core.c. Without these two patches, we will have issues when either unregistering a gadget driver (triggered with dummy_hcd only) or issuing a device-initiated disconnect through sysfs. There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because udc-core.c already handles that. A fix to MUSB as promised, to kill the compile warnings regarding deprecated interfaces. We are essentially dropping the __deprecated flag because it doesn't look like we will ever be able to live without it when we consider the amount of silicon issues we find on different MUSB instantiations. A couple of other fixes are also available, one adding the missing transceiver events to gpio_vbus and another adding a missing unregister call to MUSB's davinci glue layer. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJPmlT8AAoJEIaOsuA1yqREGD4P/i8H8Pt46V6PekeV7G/8z3O/ F317Y7xDo1P5DVpfLkzB4xjAEtlu2MhH8mhf2bNbWN3kCFBh13Nm/rarIMYS+H/Z qGdou47LyUh65BUyGp7Ul66KPtGaA5hTuTag/DdyvfJeR0ePZgzZ8gpcGm4Cn/zR LqLDB3D+qa8W2TUyibNjNHC/An9PSvEQcCkmdIAhOaQkBoRnqgtfoD6ecN5gCebQ UOSr6q9Xh97QRoMEsQ4xAEeKBh6RnB30suhDzbO0ISJ9kmQWK9TX8DdxZvMSAkCk HHmOUXtivlznNqk7+ckpl7tcwhnVKiYcXjvcS7MpSU+FHXNYcs4EqxFR/CWcBuiO nQcn8pFZ6+Bw07myQlPZtjJTEPkPcn6pq0iMWSR6W/EWIsfe9AFa4YiouiyuqsCf yCFVJc/VzoSHkYWEy/S7loFOXLhBvU0S6okR5yjg0GrW386aIzDmPHCPU6JcJrOg NAcAdWWrN+rCeqz/f7Lkp69ni8CNsuvN3bCLvQuit4e+9oM8EabIkrd6Akc2+d8j IIDiz2MwtOXkoRyJ8ua6P3ilIhfp16R/mQVA4uGe8WzF8pMzctNSzQSmzTyBEkHc YM7a7pcAwkQk6CXdpbH3fi++dwAjR7fZufODSLau/w1YJpSBFWg/ByzIfVWvMFrW KcESapF9TybpiqjPMzeX =Epei -----END PGP SIGNATURE----- Merge tag 'fixes-for-v3.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus usb: fixes for v3.4-rc cycle A few more fixes for v3.4-rc cycle.

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 ("khubd").
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.
