Laurent Pinchart 512ad27d86 USB audio gadget: Prefix all macro definitions with UAC_ in linux/usb/audio.h
linux/usb/audio.h is a public header file that includes definitions
exported to userspace. To avoid namespace clashes, prefix all macro
definitions with UAC_. Existing macros and structures prefixed with
USB_AC_ and USB_AS_ are renamed for consistency.

David Brownell 36e893d25a usb gadget: USB_GADGET_VBUS_DRAW Kconfig option
Offer a "how much VBUS power to request" configuration option
for USB gadgets that aren't using board-specific customization
of their gadget or (composite) configuration drivers.

Also remove a couple pointless "depends on USB_GADGET" bits
from the Kconfig text; booleans inside an "if USB_GADGET" will
already have that dependency.

Based on a patch from Justin Clacherty.

Change how the MIDI gadget driver builds:  don't use separate
compilation, since it works poorly when key parts are library
code (with init sections etc).  Instead be as close as we can
to "gcc --combine ...".

Arjan van de Ven b6c6393700 Rename WARN() to WARNING() to clear the namespace
We want to use WARN() as a variant of WARN_ON(), however a few drivers are
using WARN() internally.  This patch renames these to WARNING() to avoid the
namespace clash.  A few cases were defining but not using the thing, for those
cases I just deleted the definition.

David Brownell 0e530b4578 USB: gadget section fixes
Restore some section annotations:  they were switched to "__devinit"
while they should have been "__init", because of bogus warnings.  The
warnings are now fixed, so the runtime footprint of various drivers
can now shrink a bit.  On ARMv5, it's about 600 bytes except for the
Ethernet gadget, where it can save a bit more.

Takashi Iwai 9004acc70e [ALSA] Remove sound/driver.h
This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

Clean up the midi gadget, using newer APIs and conventions:

 - Use the DEBUG (from Kconfig+Makefile) and VERBOSE_DEBUG conventions.

 - Whitespace fixes

There should be no effect on object code size.

David Brownell 9d8bab58b7 usb gadget stack: remove usb_ep_*_buffer(), part 1
Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers.
This patch just removes the interface and its users; later patches will
remove controller driver support.

  - This interface is invariably not implemented correctly in the
    controller drivers (e.g. using dma pools, a mechanism which
    post-dates the interface by several years).

  - At this point no gadget driver really *needs* to use it.  In
    current kernels, any driver that needs such a mechanism could
    allocate a dma pool themselves.

Removing this interface is thus a simplification and improvement.

Note that the gmidi.c driver had a bug in this area; fixed.

David Brownell 6bea476cf6 USB: gadget driver unbind() is optional; section fixes; misc
Allow gadget drivers to omit the unbind() method.  When they're
statically linked, that's an appropriate memory saving tweak.

Similarly, provide consistent/simpler handling for a should-not-happen
error case:  removing a peripheral controller driver when a gadget
driver is still loaded.  Such code dates back to early versions of the
first implementation of the gadget API, and has never been triggered.

Includes relevant section annotation fixs for gmidi.c, file_storage.c,
and serial.c; we don't yet have an "init or exit" annotation.  Also
some whitespace fixes in gmidi.c (space at EOL, before tabs, etc).

Serge E. Hallyn 96b644bdec [PATCH] namespaces: utsname: use init_utsname when appropriate
In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use.  This patch replaces those with a the init_utsname
helper.

Changes: Removed several uses of init_utsname().  Hope I picked all the
	right ones in net/ipv4/ipconfig.c.  These are now changed to
	utsname() (the per-process namespace utsname) in the previous
	patch (2/7)

Ben Williamson f2ebf92c9e USB: gmidi: New USB MIDI Gadget class driver.
This driver is glue between the USB gadget interface
and the ALSA MIDI interface. It allows us to appear
as a MIDI Streaming device to a host system on the
other end of a USB cable.

This includes linux/usb/audio.h and linux/usb/midi.h
containing definitions from the relevant USB specifications
for USB audio and USB MIDI devices.

The following changes have been made since the first RFC
posting:

* Bug fixes to endpoint handling.
* Workaround for USB_REQ_SET_CONFIGURATION handling,
  not understood yet.
* Added SND and SND_RAWMIDI dependencies in Kconfig.
* Moved usb_audio.h and usb_midi.h to usb/*.h
* Added module parameters for ALSA card index and id.
* Added module parameters for USB descriptor IDs and strings.
* Removed some unneeded stuff inherited from zero.c, more to go.
* Provide DECLARE_* macros for the variable-length structs.
* Use kmalloc instead of usb_ep_alloc_buffer.
* Limit source to 80 columns.
* Return actual error code instead of -ENOMEM in a few places.
