From 9f8e32dfca2aab9dea8a9db335e3a783b0035507 Mon Sep 17 00:00:00 2001 From: Jaejoong Kim Date: Fri, 20 Oct 2017 16:29:15 +0900 Subject: usb: misc: usbtest: remove duplicate & operation usb_endpoint_maxp() has an inline keyword and searches for bits[10:0] by & operation with 0x7ff. So, we can remove the duplicate & operation with 0x7ff.

Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.
