USB: stop io performed by mos7720 upon close()

2008-02-01T22:35:03+00:00

This fixes a problem where the mos7720 driver will make io to a device from
which it has been logically disconnected. It does so by introducing a flag by
which the generic usb serial code can signal the subdrivers their
disconnection and appropriate locking.

USB: linux/usb/Kbuild needs only "header-y", not "unifdef-y"

2008-02-01T22:34:50+00:00

Given that none of the referenced header files test the proprocessor
conditional __KERNEL__, there's no point "unifdef"fing them.

USB: usb_serial: clean tty reference in the last close

2008-02-01T22:34:50+00:00

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.

When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
        tty = port->tty;
        if (!tty)
                return;

        tty_wakeup(tty);
which causes (manually copied):

USB: add Printer Gadget Driver

2008-02-01T22:34:49+00:00

G_PRINTER: Adds a USB printer gadget driver for use in printer firmware.

This adds a USB printer gadget driver for use in printer firmware.
The printer gadget channels data between the USB host and a userspace
program driving the print engine. The user space program reads and
writes the device file /dev/g_printer to receive or send printer data.
It can use ioctl calls to the device file to get or set printer status.

Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes

outside drivers/net/usb in drivers/net/wireless and yet need these headers.

USB: serial core should respect driver requirements

2007-10-12T21:55:34+00:00

This patch (as997) fixes a bug in the USB serial core.  The core needs
to pay attention to drivers' requirements regarding the number and
type of endpoints a device has.

At the same time, the patch changes the NUM_DONT_CARE constant (which
is stored in a single-byte field) from -1 to a safer, unsigned value.
It also improves the kerneldoc for several fields in the
usb_serial_driver structure.

Finally, the patch replaces a list_for_each() with list_for_each_entry().

USB: remove USB_QUIRK_NO_AUTOSUSPEND

2007-10-12T21:55:28+00:00

This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk.  Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended.  Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID.  I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.

The patch also cleans up the hasty way in which autosuspend gets
disabled.  Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ.  It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.
