USB: serial: ipaq: always register a single port

2017-03-28T09:00:09+00:00

Use the calc_num_ports callback to ignore unused endpoints.

The driver binds to any interface with at least one bulk-in and one
bulk-out endpoint, but some devices can have three or more endpoints of
which only either the first or second pair of endpoints is needed.

This avoids allocating resources for unused endpoints, and specifically
a port is no longer registered for the unused first endpoint pair when
there are more than three endpoints.

USB: serial: ipaq: use calc_num_endpoints to verify endpoints

2017-03-28T09:00:09+00:00

Use the calc_num_ports rather than attach callback to determine which
interface to bind to in order to avoid allocating port-resources for
interfaces that won't be bound.

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: ipaq.c: fix a timeout loop

2015-12-18T17:30:34+00:00

The code expects the loop to end with "retries" set to zero but, because
it is a post-op, it will end set to -1.  I have fixed this by moving the
decrement inside the loop.

usb: delete non-required instances of include

2014-01-08T23:01:39+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

USB: serial: constify device-id tables

2014-01-03T20:31:46+00:00

Declare device-id tables as const where possible.

USB: serial: remove driver version information

2012-10-31T19:48:06+00:00

Remove all MODULE_VERSION macros and driver-version information (except
for garmin_gps which uses it in a status reply).

It is the kernel version that matters and not some private version
scheme which rarely even gets updated.

USB: serial: ipaq.c: remove debug module parameter

2012-09-14T19:31:30+00:00

Now that the dbg() macro is no longer being used in the driver,
the debug module parameter doesn't do anything at all.  So remove
it so as to not confuse people.

USB: ipaq.c: remove dbg() usage

2012-05-15T23:27:20+00:00

dbg() is a usb-serial specific macro.  This patch converts
the ipaq.c driver to use dev_dbg() instead to tie into the
dynamic debug infrastructure.

USB: serial: rework usb_serial_register/deregister_drivers()

2012-05-08T22:46:14+00:00

This reworks the usb_serial_register_drivers() and
usb_serial_deregister_drivers() to not need a pointer to a struct
usb_driver anymore.  The usb_driver structure is now created dynamically
and registered and unregistered as needed.

This saves lines of code in each usb-serial driver.  All in-kernel users
of these functions were also fixed up at this time.  The pl2303 driver
was tested that everything worked properly.

Thanks for the idea to do this from Alan Stern.
