Subject: [PATCH] drm: sti: fix prototypes after API change

Like the mediatek hdmi driver, the sti driver now suffers from
an API change in linux-next:

drivers/gpu/drm/sti/sti_hdmi.c:1250:15: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .hw_params = hdmi_audio_hw_params,
               ^~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/sti/sti_hdmi.c:1250:15: note: (near initialization for 'audio_codec_ops.hw_params')

This follows the API change, adding the extra function arguments.
I suppose we want this to be part of the ASoC merge in linux-next
for now too.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 2c348e505328 ("drm: sti: Add ASoC generic hdmi codec support.")
Fixes: efc9194bcff8 ("ASoC: hdmi-codec: callback function will be called with private data")
