ALSA: usb-audio: scarlett2: Add support for Solo and 2i2 Gen 3
Add initial support for the Focusrite Scarlett Solo and 2i2 devices: - They have no mixer - They don't support reporting sync status or levels - The configuration space is laid out differently to the other models - There is no level (line/inst) switch on input 1 of the Solo Co-developed-by: Vladimir Sadovnikov <sadko4u@gmail.com> Signed-off-by: Vladimir Sadovnikov <sadko4u@gmail.com> Signed-off-by: Geoffrey D. Bennett <g@b4.vu> Link: https://lore.kernel.org/r/190b90f6f1f8f8d4dfb5f0a7761ff8ae5c40fdde.1624379707.git.g@b4.vu Signed-off-by: Takashi Iwai <tiwai@suse.de>
