USB: audio: guard kernel-only code with KERNEL

2009-09-23T13:46:31+00:00

include/linux/usb/audio.h is exported to userspace,
so part of this file that is for internal kernel
usage need to be guarded with ifdef __KERNEL__.
This way make headers_install will stript it out.

USB audio gadget: Un-inline generic_[gs]et_cmd

2009-09-23T13:46:20+00:00

Those functions are used only used to fill the set/get members of
usb_audio_control. It doesn't make much sense to inline them.

USB audio gadget: Prefix all macro definitions with UAC_ in linux/usb/audio.h

2009-09-23T13:46:20+00:00

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.

USB: Move vendor subclass definition from usb/audio.h to usb/ch9.h

2009-09-23T13:46:19+00:00

USB_SUBCLASS_VENDOR_SPEC is common to several USB classes and as such belongs
to usb/ch9.h.

USB: Standardize inclusion protection and add where missing.

2008-04-25T04:16:42+00:00

For the header files in include/linux/usb, add missing multiple
inclusion protection and standardize what's already there.  The
apparent standards:

  * macro name of __LINUX_USB_headerfile_H
  * inclusion protection placed after leading comment block
  * macro name added as a comment on the final #endif
  * any obvious trivial whitespace cleanup associated with the above

USB: gmidi: New USB MIDI Gadget class driver.

2006-09-27T18:58:52+00:00

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.
