USB: serial: fix module-license macros

2017-11-04T10:58:00+00:00

Several GPL-2.0 drivers used "GPL" rather than "GPL v2" in their
MODULE_LICENSE macros; fix the macros to match the licenses.

USB: serial: Remove redundant license text

2017-11-04T10:55:38+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

USB: serial: visor: clean up treo endpoint hack

2017-03-28T09:14:11+00:00

Use the new endpoint-remap functionality to configure the ports for
treo devices instead of poking around in the port structures after the
ports have been setup.

USB: serial: visor: clean up clie_5 endpoint hack

2017-03-28T09:14:11+00:00

Use the new endpoint-remap functionality to configure the ports for
clie_5 devices.

Note that the same bulk-out endpoint is being used for both ports.

USB: serial: visor: drop redundant calc_num_ports callback

2017-03-28T09:14:11+00:00

Drop the redundant calc_num_ports callback from the clie_5 type, for
which the callback always returns zero and hence falls back to the type
num_ports value (2).

USB: serial: allow subdrivers to modify port-endpoint mapping

2017-03-28T08:54:39+00:00

Allow subdrivers to modify the port-endpoint mapping by passing the
endpoint descriptors to calc_num_ports.

The callback can now also be used to verify that the required endpoints
exists and abort probing otherwise.

This will allow us to get rid of a few hacks in subdrivers that are
already modifying the port-endpoint mapping (or aborting probe due to
missing endpoints), but only after the port structures have been setup.

USB: serial: visor: fix crash on detecting device without write_urbs

2016-01-25T10:40:45+00:00

The visor driver crashes in clie_5_attach() when a specially crafted USB
device without bulk-out endpoint is detected. This fix adds a check that
the device has proper configuration expected by the driver.

USB: visor: fix null-deref at probe

2016-01-25T10:36:41+00:00

Fix null-pointer dereference at probe should a (malicious) Treo device
lack the expected endpoints.

Specifically, the Treo port-setup hack was dereferencing the bulk-in and
interrupt-in urbs without first making sure they had been allocated by
core.

USB: visor: Match I330 phone more precisely

2015-04-29T10:36:52+00:00

Samsung has just released a portable USB3 SSD, coming in a very small
and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
already used by the Palm Visor driver for the Samsung I330 phone cradle.
Having pl2303 or visor pick up this device ID results in conflicts with
the usb-storage driver, which handles the newly released portable USB3
SSD.

To work around this conflict, I've dug up a mailing list post [1] from a
long time ago, in which a user posts the full USB descriptor
information. The most specific value in this appears to be the interface
class, which has value 255 (0xff). Since usb-storage requires an
interface class of 0x8, I believe it's correct to disambiguate the two
devices by matching on 0xff inside visor.
