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.
