There is no need to use temporary strings to construct the kcontrol names,
devm_kasprintf can be used to replace the snprintf + devm_kstrdup pairs.
This change will also fixes the following compiler warning/error (W=1):
sound/soc/codecs/hdac_hdmi.c: In function ‘hdac_hdmi_jack_port_init’:
sound/soc/codecs/hdac_hdmi.c:1793:63: error: ‘ Switch’ directive output may be truncated writing 7 bytes into a region of size between 1 and 32 [-Werror=format-truncation=]
1793 | snprintf(kc_name, sizeof(kc_name), "%s Switch", xname);
| ^~~~~~~
In function ‘create_fill_jack_kcontrols’,
inlined from ‘hdac_hdmi_jack_port_init’ at sound/soc/codecs/hdac_hdmi.c:1871:8:
sound/soc/codecs/hdac_hdmi.c:1793:25: note: ‘snprintf’ output between 8 and 39 bytes into a destination of size 32
1793 | snprintf(kc_name, sizeof(kc_name), "%s Switch", xname);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
The warnings got brought to light by a recent patch upstream:

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.
