Just curious, why is your platform data here not just a pointer to a struct wl1273 ?
- struct wl1273_priv *wl1273;
- int r;
- dev_dbg(codec->dev, "%s.\n", __func__);
- if (!core) {
dev_err(codec->dev, "Platform data is missing.\n");return -EINVAL;- }
- wl1273 = kzalloc(sizeof(struct wl1273_priv), GFP_KERNEL);
- if (wl1273 == NULL) {
dev_err(codec->dev, "Cannot allocate memory.\n");return -ENOMEM;- }
- wl1273->mode = WL1273_MODE_BT;
- wl1273->core = *core;

Above 6 lines now done by core, so not needed now (I mentioned that for V5, but maybe not explicitly)
Thanks
