USB: convert drivers/usb/* to use module_usb_driver()

2011-11-18T17:34:02+00:00

This converts the drivers in drivers/usb/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

USB: DL100B webmail notifier: initialize return value

2011-01-23T02:32:54+00:00

If case of an unknown usb_device_id->driver_info (which could only
occur if the info got corrupted somewhere outside the usbled driver),
a debug message depended on an uninitialized value. This was harmless,
but ugly, and gets fixed with this patch.

USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004)

2010-12-22T04:48:21+00:00

So far the USBLED driver only supports Delcom's "USB Visual Signal
Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The
driver generates virtual files "red", "green", and "blue" under the
device's /sys/ directory, where color values can be read from and
written to.

This patch adds support for Dream Cheeky's "DL100B Webmail Notifier"
(http://www.dreamcheeky.com/webmail-notifier -- available from several
shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL).
This device isn't as pretty as Delcom's, but it's *far* cheaper, and
its 3 LEDs can be set in 32 brightness steps each. The grey envelope
contour can easily be removed, leaving a rather neutral white box (with
a few small holes), which is useful for generic signalling purposes.
Of course, the small circuit board can easily be put into a prettier
case.

The DL100B device pretends to be a HID, but the HID descriptor shows
that it's not overly useful as such (see below). The patch therefore
removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary
commands to usbled.c. The protocol info comes from the developer's
manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).

HID descriptor:

USB misc: make USB device id constant

2010-03-02T22:54:17+00:00

The id_table field of the struct usb_device_id is constant in 
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)

//

USB: fix usbled disconnect read race #2

usbled has a race where show methods for attributes in sysfs can
