[PATCH] ALSA: intel_hdmi: Fix off-by-one error in __hdmi_lpe_audio_probe()

[Thorsten Blum <thorsten.blum@linux.dev>]

In __hdmi_lpe_audio_probe(), strscpy() is incorrectly called with the
length of the source string (excluding the NUL terminator) rather than
the size of the destination buffer. This results in one character less
being copied from 'card->shortname' to 'pcm->name'.

Since 'pcm->name' is a fixed-size buffer, we can safely omit the size
argument and let strscpy() infer it using sizeof(). This ensures the
card name is copied correctly.
