video: adf: Cleanup sw_sync timeline at adf_device_destroy

If a sw_sync timeline was created by ADF (for drivers that do not implement
ops->complete_fence) we should clean it up when the ADF device is
destroyed.

usb: gadget: f_audio_source: change max ISO packet size

Re-applying from
https://gitorious.org/shr/linux/commit/eb4c9d2db894c3492c0a848581bd4f6790f93d5f

Most USB-AUDIO devices are limited to 256 byte for max iso buffer size.
If a IN_EP_MAX_PACKET_SIZE is bigger than a USB-AUDIO device's max iso
buffer size, it will cause noise. This patch will prevent this case as
possibe by reducing packet size. When using 44.1khz, 2ch, 16bit audio
data, if max packet size is bigger than 176 bytes, it's no problem.

usb: gadget: f_audio_source: Fixed USB Audio Class Interface Descriptor

Fixed Android Issue #56549.

When both Vendor Class and Audio Class are activated for AOA 2.0,
the baInterfaceNr of the AudioControl Interface Descriptor points
to wrong interface numbers. They should be pointing to
Audio Control Device and Audio Streaming interfaces.

Replaced baInterfaceNr with the correct value.
