[ Upstream commit 261d3a85d959841821ca0d69f9d7b0d4087661c4 ]
As we first take the lock with spin_lock_irqsave in msgdma_tasklet, Lockdep
might complain about this. Inspired by commit 9558cf4ad0
("dmaengine: zynqmp_dma: fix lockdep warning in tasklet")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
