[pulseaudio-discuss] [PATCH] alsa-card: skip eld initialization if hctl_handle is NULL.

[Maarten Lankhorst]

Due to a misconfiguration on my side my hdmi card didn't load with
snd-hda-codec-hdmi but through the fallback mechanism. Pulseaudio
would crash during early because hctl_handle was null, so skip
init_eld_ctls when hctl_handle is null to prevent a crash.

Thanks to David Henningsson for helping me find the underlying issue.
