From 5610921a4435ef45c33702073e64f835f3dca7f1 Mon Sep 17 00:00:00 2001 From: Mateusz Gorski Date: Wed, 22 Jul 2020 19:35:24 +0200 Subject: ASoC: Intel: skl_hda_dsp_generic: Fix NULLptr dereference in autosuspend delay Different modules for HDMI codec are used depending on the "hda_codec_use_common_hdmi" option being enabled or not. Driver private context for both of them is different. This leads to null-pointer dereference error when driver tries to set autosuspend delay for HDMI codec while the option is off (hdac_hdmi module is used for HDMI). Change the string in conditional statement to "ehdaudio0D0" to ensure that only the HDAudio codec is handled by this function.
