[PATCH v5 1/4] usb: gadget: f_uac2: remove platform driver/device creation

Simplify f_uac2 by removing platform driver/device creation; use composite's usb_gadget device as parent for sound card and for debug prints. This removes extra layer of code without any functional change. Signed-off-by: Ruslan Bilovol <ruslan.bilo...@gmail.com> --- drivers/usb/gadget/fu

[PATCH v5 4/4] usb: gadget: add f_uac1 variant based on a new u_audio api

ere is no any reason to keep them in the same file/module, and separate function was created. g_audio can be built using one of existing UAC functions (f_uac1, f_uac1_legacy or f_uac2) Signed-off-by: Ruslan Bilovol <ruslan.bilo...@gmail.com> --- Documentation/ABI/testing/configfs-us
