Ugh, hardly to read. Slightly better to use to_delayed_work()?
struct hdmi_eld *eld = container_of(to_delayed_work(work),
struct hdmi_eld, work);

Looking through the code, I wonder how about keeping work and codec
pointer in struct hdmi_spec_per_pin instead of struct hdmi_eld. Then
we don't need to expose it in hda_local.h, and changes would be
slightly more compact.
hdmi_present_sense() can be modified to receive hdmi_sepc_per_pin*
directly instead of individual nid and eld pointer.
thanks,
Takashi
