* USB: DL100B webmail notifier: initialize return valueMelchior FRANZ2011-01-22
| | | | | | | | | | 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. Signed-off-by: Melchior FRANZ <mfranz@aon.at> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004)Melchior FRANZ2010-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* USB misc: make USB device id constantNémeth Márton2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id_table field of the struct usb_device_id is constant in <linux/usb.h> 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/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Németh Márton <nm127@freemail.hu> Cc: Julia Lawall <julia@diku.dk> Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
