From 165c0946a863cdfd056e472d8a9673d7197ef066 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 6 Feb 2020 17:28:01 +0100 Subject: [PATCH] ALSA: hda/hdmi: Reduce hda_jack_tbl lookup at unsol event handling Pass hda_jack_tbl object to hdmi_intrinsic_event() along with res from hdmi_unsol_event() so that we can reduce the lookup of the same hda_jack_tbl object again. Minor code refactoring.
