JIRA: https://issues.redhat.com/browse/RHEL-118908

commit 292e4adb954b8584b74bff0d1f9044af297fa248

    ALSA: ppc: Use safer strscpy() instead of strcpy()

    Use a safer function strscpy() instead of strcpy() for copying to
    arrays.

    Only idiomatic code replacement, and no functional changes.
