2016-02-16fix false disconnect due to a signal sent to the reading processkeunyoung
- In the current implementation, when a signal is sent to the reading process, read is cancelled by calling usb_ep_dequeue, which lead into calling acc_complete_out with ECONNRESET, but the current logic treats it as disconnection, which makes the device inaccessible until cable is actually disconnected. - The fix calls disconnect only when ESHUTDOWN error is passed. - If data has already arrived while trying cancelling, the data is marked as available, and it will be read out on the next read. This is necessary as USB bulk is assumed to guarantee no data loss. Signed-off-by: keunyoung <keunyoung@google.com>

On windows 7 platform, previously allocated ip address is maintained. However, Host MAC address of 'usb0' interface is changed when the tethering driver re-enumerated. Thus, the tethering network driver can't be allocated ip address from dhcp. It causes connection delay between host and phone for usb tethering. This patch prevents from changing Host MAC address of 'usb0' interface. In other words, this patch maintains the Host MAC address allocated when first tethering driver although the driver is re-enumerated. However, after reboot, the Host MAC address can be changed.

For high throughput scenarios on rx data path driver is spending lot of time in interrupt context due to rx data processing by tasklet and continuous completion and re-submission of the usb requests which results in watchdog bark. Hence move the rx data processing and usb request submission to a workqueue bottom half handler.

2016-02-16USB: rndis: Free the rndis response queue during REMOTE_NDIS_RESET_MSGxerox_lin
When rndis data transfer is in progress, some Windows7 Host PC is not sending the GET_ENCAPSULATED_RESPONSE command for receiving the response for the previous SEND_ENCAPSULATED_COMMAND processed. The rndis function driver appends each response for the SEND_ENCAPSULATED_COMMAND in a queue. As the above process got corrupted, the Host sends a REMOTE_NDIS_RESET_MSG command to do a soft-reset. As the rndis response queue is not freed, the previous response is sent as a part of this REMOTE_NDIS_RESET_MSG's reset response and the Host blocks any more Rndis transfers. Hence free the rndis response queue as a part of this soft-reset so that the current response for REMOTE_NDIS_RESET_MSG is sent properly during the response command.

2016-02-16usb: gadget: f_audio_source: Fixed USB Audio Class Interface DescriptorAnson Jacob
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.

2016-02-16usb: gadget: f_audio_source: change max ISO packet sizeAnson Jacob
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.

2016-02-16USB: remove duplicate out endpoint creation in MTP modePeter Oh
Android MTP gadget uses 3 endpoints which are 1 in endpoint, 1 out endpoint, and 1 interrupt endpoint. However when MTP gadget creates its endpoints, it creates the out endpoint twice and overwrites the first created out endpoint with the second one, so that it causes a leak of endpoint resources.
