Wait to signal done until we get all of the interrupts we are expecting to get for a transaction. If we don't wait for the input done flag, we can be in between transactions when the done flag comes in and this can mess up the next transaction. While here cleaning up the code which sets controller->xfer = NULL and restores it in the ISR. This looks to be some debug code which is not required.

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.
