From e3f8064d8b29036f037fd1ff6000e5d959d84843 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Fri, 15 Nov 2024 23:06:53 +0800 Subject: [PATCH] ALSA: hda: Poll jack events for LS7A HD-Audio LS7A HD-Audio disable interrupts and use polling mode due to hardware drawbacks. As a result, unsolicited jack events are also unusable. If we want to support headphone hotplug, we need to also poll jack events. Here we use 1500ms as the poll interval if no module parameter specify it.
