Kai Vehmanen ce1558c285 ALSA: hda/hdmi: fix incorrect locking in hdmi_pcm_close ... A race exists between closing a PCM and update of ELD data. In hdmi_pcm_close(), hinfo->nid value is modified without taking spec->pcm_lock. If this happens concurrently while processing an ELD update in hdmi_pcm_setup_pin(), converter assignment may be done incorrectly. This bug was found by hitting a WARN_ON in snd_hda_spdif_ctls_assign() in a HDMI receiver connection stress test: [2739.684569] WARNING: CPU: 5 PID: 2090 at sound/pci/hda/patch_hdmi.c:1898 check_non_pcm_per_cvt+0x41/0x50 [snd_hda_codec_hdmi] ...
