| Subject | [PATCH v4 41/43] usb: gadget: uvc: simplify descriptors generation |
| Date | 2016-02-03 13:50 +0100 |
| Message-ID | <qY52J-212-97@gated-at.bofh.it> (permalink) |

| Organization | linux.* mail to news gateway |
As we don't need distinction between interface descriptors for different
speeds, we can remove some amount of unnecessary code. Additionally we
simplify configfs interface of UVC function.
