[PATCH] ALSA: hda/cirrus: Fix broken audio on hardware with two CS42L42 codecs.
Recently in v6.3-rc1 there was a change affecting behaviour of hrtimers (commit 0c52310f260014d95c1310364379772cb74cf82d) and causing few issues on platforms with two CS42L42 codecs. Canonical/Dell has reported an issue with Vostro-3910. We need to increase this value by 15ms.

Thanks, applied now (with a slight correction of Fixes tag; it needs quotes around the commit subject).
