After commit 7e4da3fcf7c9 ("usb: gadget: composite:
Test get_alt() presence instead of set_alt()") f_uac1
function became broken because it doesn't have
get_alt() callback implementation and composite
framework never set altsetting 1 for audiostreaming
interface. On host site it looks like:
[424339.017711] 21:1:1: usb_set_interface failed (-32)
Since host can't set altsetting 1, it can't start
playing audio.
In order to fix it implemented get_alt along with
minor improvements (error conditions checking)
similar to what existing f_uac2 has.

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.

Calculate wMaxPacketSize before endpoint matching the
descriptor is found.
This allows audio gadget to be used with controllers
which have a shortage or unavailability of endpoints
that can handle max packet size of 1023 (FS) or 1024
(HS).
With this audio gadget can be used on TI's OMAP-L138 SoC
which has a MUSB HS controller with endpoints having max
packet size much less than 1023 or 1024. See mode_2_cfg in
drivers/usb/musb/musb_core.c

There are only two requests for uac2, it may not be enough at high
loading system which usb interrupt handler can't be serviced on
time, then the data will be lost since it is isoc transfer for audio.
In this patch, we introduce a parameter for the number for usb request,
and the user can override it if current number for request is not enough
for his/her use case.
Besides, update this parameter for legacy audio gadget and documentation.

This commit allows SAE Authentication for NL80211_CMD_CONNECT
interface, provided host driver advertises the support.
Host drivers may offload the SAE authentication to user space
through NL80211_CMD_EXTERNAL_AUTH interface and thus expect
the user space to advertise support to handle offload through
NL80211_ATTR_EXTERNAL_AUTH_SUPPORT in NL80211_CMD_CONNECT
request. Such drivers should reject the connect request on no
offload support from user space.

This interface allows the host driver to offload the authentication to
user space. This is exclusively defined for host drivers that do not
define separate commands for authentication and association, but rely on
userspace SME (e.g., in wpa_supplicant for the ~WPA_DRIVER_FLAGS_SME
case) for the authentication to happen. This can be used to implement
SAE without full implementation in the kernel/firmware while still being
able to use NL80211_CMD_CONNECT with driver-based BSS selection.
Host driver sends NL80211_CMD_EXTERNAL_AUTH event to start/abort
authentication to the port on which connect is triggered and status
of authentication is further indicated by user space to host
driver through the same command response interface.
User space entities advertise this capability through the
NL80211_ATTR_EXTERNAL_AUTH_SUPP flag in the NL80211_CMD_CONNECT request.
Host drivers shall look at this capability to offload the authentication.
