[PATCH 6.19 06/86] ALSA: hda/intel: enforce stricter period-size alignment for Intel NVL

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

commit 082c192c0dd03f685514c9ce2eb0a80fd28e2175 upstream.

Intel ACE4 based products set more strict constraints on HDA BDLE start
address and length alignment. Modify capability flags to drop
AZX_DCAPS_NO_ALIGN_BUFSIZE for Intel Nova Lake platforms.

Fixes: 7f428282fde3 ("ALSA: hda: controllers: intel: add support for Nova Lake")
