Ziyi Guo 2d8f056e9c ASoC: fsl: imx-rpmsg: use snd_soc_find_dai_with_mutex() in probe 
[ Upstream commit 84faa91585 ]

imx_rpmsg_probe() calls snd_soc_find_dai() without holding client_mutex.
However, snd_soc_find_dai() has lockdep_assert_held(&client_mutex)
indicating callers must hold this lock, as the function iterates over the
global component list.

All other callers of snd_soc_find_dai() either hold client_mutex via the
snd_soc_bind_card() path or use the snd_soc_find_dai_with_mutex() wrapper.

Use snd_soc_find_dai_with_mutex() instead to fix the missing lock
protection.

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 reStructuredText 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.
