Bin Liu e75c01761a usb: musb: dsps: do not disable CPPI41 irq in driver teardown
commit 783f3b4e9e upstream.

TI AM335x CPPI 4.1 module uses a single register bit for CPPI interrupts
in both musb controllers. So disabling the CPPI irq in one musb driver
breaks the other musb module.

Since musb is already disabled before tearing down dma controller in
musb_remove(), it is safe to not disable CPPI irq in
musb_dma_controller_destroy().

Fixes: 255348289f ("usb: musb: dsps: Manage CPPI 4.1 DMA interrupt in DSPS")

README

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.
