Use a struct to parse the audio units, and return usable descriptors for all types. There's no need to limit the result set, except for some kind of sanity check. Signed-off-by: NDaniel Mack <daniel@caiaq.de> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

So far, UAC2 controls are marked read-only if any of the channels are marked read-only in the descriptors. Change this behaviour and - mark them writeable unless all channels are read-only - store the read-only mask in usb_mixer_elem_info and - check the mask again in set_cur_mix_value(), and bail out for write-protected channels.

For both UAC1 and UAC2, interrupt endpoint messages are now parsed with structs rather that with anonymous buffer array accesses. For UAC2, only CUR interrupt notifications are supported for now. snd_usb_mixer_status_complete() was renamed to snd_usb_mixer_interrupt(). Fixed one indentation flaw on the way.

Clean up the usb audio driver by factoring out a lot of functions to separate files. Code for procfs, quirks, urbs, format parsers etc all got a new home now. Moved almost all special quirk handling to quirks.c and introduced new generic functions to handle them, so the exceptions do not pollute the whole driver. Renamed usbaudio.c to card.c because this is what it actually does now. Renamed usbmidi.c to midi.c for namespace clarity. Removed more things from usbaudio.h. The non-standard drivers were adopted accordingly. Signed-off-by: NDaniel Mack <daniel@caiaq.de> Cc: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Use the definitions from linux/usb/audio.h all over the ALSA USB audio driver and add some missing definitions there as well. Use the endpoint attribute macros from linux/usb/ch9 and remove the own things from sound/usb/usbaudio.h. Now things are also nicely prefixed which makes understanding the code easier.

In preparation of support for v2.0 audio class, use the structs from linux/usb/audio.h and add some new ones to describe the fields that are actually parsed by the descriptor decoders. Also, factor out code from usb_create_streams(). This makes it easier to adopt the new iteration logic needed for v2.0.

This patch extends 42a6e66f by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. This patch also rewrites some calls to usb_endpoint_dir_in as negated calls to !usb_endpoint_dir_out, and vice versa, to better correspond to the intent of the original code. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_CONTROL\|0\)) + !usb_endpoint_xfer_control(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_ISOC\|1\)) + !usb_endpoint_xfer_isoc(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_BULK\|2\)) + !usb_endpoint_xfer_bulk(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_INT\|3\)) + !usb_endpoint_xfer_int(epd) // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NTakashi Iwai <tiwai@suse.de>
