The patch 955ac624058f: "ASoC: fsl_easrc: Add EASRC ASoC CPU DAI
drivers" from Apr 16, 2020, leads to the following Smatch complaint:
sound/soc/fsl/fsl_easrc.c:1529 fsl_easrc_hw_free()
warn: variable dereferenced before check 'ctx' (see line 1527)
sound/soc/fsl/fsl_easrc.c
1526 struct fsl_asrc_pair *ctx = runtime->private_data;
1527 struct fsl_easrc_ctx_priv *ctx_priv = ctx->private;
^^^^^
Dereference
1528
1529 if (ctx && (ctx_priv->ctx_streams & BIT(substream->stream))) {
^^^
This check is too late, to prevent a NULL dereference.
1530 ctx_priv->ctx_streams &= ~BIT(substream->stream);
1531 fsl_easrc_release_context(ctx);

README
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.
