[alsa-devel] [PATCH v2 4/7] ALSA: hda - Add hdmi chmap verb programming ops to chmap object
Subhransu S. Prusty
subhransu.s.prusty at intel.com
Wed Mar 2 13:03:25 CET 2016
Add slot and channel count programming to hdmi_chmap object and
move the chmap_ops to core. Use register_chmap_ops API to
register for default ops. Override specific chmap ops in the
driver.
