When babble condition happens, the musb controller might automatically turns off VBUS. On DA8xx platform, the controller generates drvvbus interrupt for turning off VBUS along with the babble interrupt. In this case, we should handle the babble interrupt first and recover from the babble condition. This change ignores the drvvbus interrupt if babble interrupt is also generated at the same time, so the babble recovery routine works properly.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
