cppcheck complains twice:
sound/soc/sof/control.c:436:2: style: Assignment of function parameter
has no effect outside the function. [uselessAssignmentArg]
size -= sizeof(const struct snd_ctl_tlv);
^
sound/soc/sof/control.c:436:7: style: Variable 'size' is assigned a
value that is never used. [unreadVariable]
size -= sizeof(const struct snd_ctl_tlv);
Somehow we dropped the checks for the size argument when upstreaming
the code, somewhere between v5 and v6.
Re-add a size check to avoid providing userspace with more data that
it asked for.
Also fix all error codes, we should return -ENOSPC instead of -EINVAL.
Fixes:

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.
