[alsa-devel] ALSA Support for Roland Gaia SH-01

[John F Leach]

Thanks for the help everyone.  I was able to get the device's USB audio
and MIDI to work, but need additional time for testing and tweaking of
the code.  

Here's the patch so far, please let me know if there are any other
enhancements I should consider.

{
        /* Roland GAIA SH-01 */
        USB_DEVICE(0x0582, 0x0111),
        .driver_info = (unsigned long) & (const struct
snd_usb_audio_quirk) {
                .vendor_name = "Roland",
                .product_name = "SH-01",
                .ifnum = QUIRK_ANY_INTERFACE,
                .type = QUIRK_COMPOSITE,
                .data = (const struct snd_usb_audio_quirk[]) {
                        {
                                .ifnum = 0,
                                .type = QUIRK_AUDIO_STANDARD_INTERFACE
                        },
                        {
                                .ifnum = 1,
                                .type = QUIRK_AUDIO_STANDARD_INTERFACE
                        },
                        {
                                .ifnum = 2,
                                .type = QUIRK_MIDI_FIXED_ENDPOINT,
                                .data = & (const struct
snd_usb_midi_endpoint_info) {
                                       .out_cables = 0x0003,
                                       .in_cables  = 0x0003
                                }
                        },
                        {
                                .ifnum = -1
                        }
                }
        }
},
