ALSA: usb-audio: mixer: Remove temporary string use in parse_clock_source_unit
The kctl->id.name can be directly passed to snd_usb_copy_string_desc() and
if the string has been fetched the suffix can be appended with the
append_ctl_name() call.
The temporary name string becomes redundant and can be removed.
This change will also fixes the following compiler warning/error (W=1):
sound/usb/mixer.c: In function ‘parse_audio_unit’:
sound/usb/mixer.c:1972:29: error: ‘ Validity’ directive output may be truncated writing 9 bytes into a region of size between 1 and 44 [-Werror=format-truncation=]
1972 | "%s Validity", name);
| ^~~~~~~~~
In function ‘parse_clock_source_unit’,
inlined from ‘parse_audio_unit’ at sound/usb/mixer.c:2892:10:
sound/usb/mixer.c:1971:17: note: ‘snprintf’ output between 10 and 53 bytes into a destination of size 44
1971 | snprintf(kctl->id.name, sizeof(kctl->id.name),
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1972 | "%s Validity", name);
| ~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
The warnings got brought to light by a recent patch upstream:
commit 6d4ab2e97dcf ("extrawarn: enable format and stringop overflow warnings in W=1")
