We have moved usb_gadget_disconnect to individual gadget driver's
disconnect, besides, it is suitable to call gadget driver's disconnect
before stopping udc, so using udc->driver->disconnect instead of
usb_gadget_disconnect at soft disconnect.

The usb_gadget_disconnect will be called at individual gadget
driver's disconnect, so delete it at udc core.

Hi Felipe & Alan,
It is the follow-up for:
http://www.spinics.net/lists/linux-usb/msg112193.html
This patchset adds reset API at usb_gadget_driver, the UDC driver
can call it at bus_reset handler instead of calling disconnect.
The benefits of this patchset are:

Adding reset API for UDC bus reset handler is useful for below
two issues.
Current disconnect API at usb_gadget_driver is also invoked at
udc's bus reset handler, but the document says it is invoked when
the host is disconnected.
Besides, we may expect the gadget_driver to do different things

This is a note to let you know that I've just added the patch titled
Revert "usb: gadget: u_ether: synchronize with transmit when stopping

In afunc_bind() and afunc_set_alt(), &uac2->pdev.dev are used multiple
times. Adding a short-hand for them makes lines shorter so we can
remove some line wraps.

The UAC2 function driver currently responds to all packets at all times
with wMaxPacketSize packets. That results in way too fast audio
playback as the function driver (which is in fact supposed to define
the audio stream pace) delivers as fast as it can.
Consider the following setup: the host use
Restructure some code to make it easier to read.
While at it, return -ENOMEM instead of -EINVAL if
usb_ep_alloc_request() fails, and omit the logging in such cases
(the mm core will complain loud enough).

For the capture endpoint, set the UAC_EP_CS_ATTR_FILL_MAX bit in
bmAttributes to that the host only send IN tokens with wMaxPacketSize
bytes. If that bit isn't set, snd-usb will calculate a smaller packet
size, which is answered by a fixed-size (512 bytes) response from the
gadget driver. That cons
Hi,
Sebastian Reimers recently reported issues with the f_uac2 gadget with
BBB's musb stack when connected to a Linux host, with the host in
capture and the gadget in playback mode. I had a look, and can confirm
two independent issues.
