USB: cdc-acm: Adding second ACM channel support for Nokia N8

2011-02-17T23:36:49+00:00

commit 721d92fc6373dee15846216f9d178ec240ec0fd7 upstream.

This adds the N8 to the list of devices in cdc-acm, in order to get the
secondary ACM device exposed.

USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint descriptors.

2010-09-20T20:17:49+00:00

commit 577045c0a76e34294f902a7d5d60e90b04d094d0 upstream.

Certain USB devices, such as the Nokia X6 mobile phone, don't expose any
endpoint descriptors on some of their interfaces. If the ACM driver is forced
to probe all interfaces on a device the a NULL pointer dereference will occur
when the ACM driver attempts to use the endpoint of the alternative settings.
One way to get the ACM driver to probe all the interfaces is by using the
/sys/bus/usb/drivers/cdc_acm/new_id interface.

This patch checks that the endpoint pointer for the current alternate settings
is non-NULL before using it.

USB: cdc-acm: Add pseudo modem without AT command capabilities

USB: cdc-acm: Adding second ACM channel support for various Nokia and one Samsung phones

2010-09-20T20:17:49+00:00

commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.

The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.

This adds support for the second ACM channel for the following devices:
    Nokia E63
    Nokia E75
    Nokia 6760 Slide
    Nokia E52
    Nokia E55
    Nokia E72
    Nokia X6
    Nokia N97 Mini
    Nokia 5800 Xpressmusic
    Nokia E90
    Samsung GTi8510 (INNOV8)

USB: Expose vendor-specific ACM channel on Nokia 5230

2010-09-20T20:17:48+00:00

commit 83a4eae9aeed4a69e89e323a105e653ae06e7c1f upstream.

Nokia S60 phones expose two ACM channels. The first is
a modem, the second is 'vendor-specific' but is treated
as a serial device at the S60 end, so we want to expose
it on Linux too.

USB: Exposing second ACM channel as tty for Nokia S60 phones.

2010-09-20T20:17:48+00:00

commit c1479a92cf0a7792298d364e44a781550621cb58 upstream.

Nokia S60 phones expose two ACM channels. The first is a modem and is picked
up by the standard AT-command interface information in the CDC-ACM driver. The
second is marked as having a vendor-specific protocol. Normally, we don't
expose those as ttys. (On some other devices, they may be claimed by the
rndis_host driver and used as a network interface).

But on S60 this second ACM channel is the way that third-party S60 application
developers are expected to communicate over USB. It acts as a serial device
at the S60 end, and so it should on Linux too.

The list of devices is largely derived from:
http://wiki.forum.nokia.com/index.php/S60_Platform_and_device_identification_codes
http://wiki.forum.nokia.com/index.php/Nokia_USB_Product_IDs
and includes only the S60 3rd Edition+ devices documented there.

There are many devices for which the USB device ID is not documented,
including:
    Nokia 6290
    Nokia E63
    Nokia 5630 XpressMusic
    Nokia 5730 XpressMusic
    Nokia 6710 Navigator
    Nokia 6720 classic
    Nokia 6730 Classic
    Nokia 6760 slide
    Nokia 6790 slide
    Nokia 6790 Surge
    Nokia E52
    Nokia E55
    Nokia E71x (AT&T)
    Nokia E72
    Nokia E75
    Nokia E75 US+LTA variant
    Nokia N79
    Nokia N86 8MP
    Nokia 5230 (RM-588)
    Nokia 5230 (RM-594)
    Nokia 5530 XpressMusic
    Nokia 5530 XpressMusic (china)
    Nokia 5800 XM
    Nokia N97 (RM-506)
    Nokia N97 mini
    Nokia X6
It would be good to add those subsequently.

USB: cdc-acm: fix resource reclaim in error path of acm_probe

2010-07-05T18:11:07+00:00

commit c2572b78aa0447244a38e555ebb1b3b48a0088a5 upstream.

This patch fixes resource reclaim in error path of acm_probe:

1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there
   is no need to call acm_read_buffers_free(acm) here.  Fix it by goto
   alloc_fail6 instead of alloc_fail7.
2. In the case of "out of memory (write urbs usb_alloc_urb)",
   usb_alloc_urb may fail in any iteration of the for loop.  Current
   implementation does not properly free allocated snd->urb.  Fix it by
   goto alloc_fail8 instead of alloc_fail7.
3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate)
   fail, acm->country_codes is kfreed. As a result, device_remove_file
   for dev_attr_wCountryCodes will not be executed in acm_disconnect.
   Fix it by calling device_remove_file for dev_attr_wCountryCodes
   before goto skip_countries.
