Peter Ujfalusi 091c2848b0 ALSA: core: Use dev_name of card_dev as debugfs directory name 
There is no need to use temporary string for the debugfs directory name as
we can use the device name of the card.

This change will also fixes the following compiler warning/error (W=1):

sound/core/init.c: In function ‘snd_card_init’:
sound/core/init.c:367:28: error: ‘%d’ directive writing between 1 and 10 bytes into a region of size 4 [-Werror=format-overflow=]
  367 |         sprintf(name, "card%d", idx);
      |                            ^~
sound/core/init.c:367:23: note: directive argument in the range [0, 2147483646]
  367 |         sprintf(name, "card%d", idx);
      |                       ^~~~~~~~
sound/core/init.c:367:9: note: ‘sprintf’ output between 6 and 15 bytes into a destination of size 8
  367 |         sprintf(name, "card%d", idx);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

The idx is guarantied to be less than SNDRV_CARDS (max 256 or 8) by the
code in snd_card_init(), however the compiler does not see that.

The warnings got brought to light by a recent patch upstream:
commit 6d4ab2e97d ("extrawarn: enable format and stringop overflow warnings in W=1")

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.
