The function "drm_of_find_panel_or_bridge" has been deprecated in favor of "devm_drm_of_get_bridge".
Switch to the new function and reduce boilerplate.

Yikes, I was about to rely on this panel variable to determine if the device is a panel or a display port connector. (Well, I am relying on it, and patches are hoping to be reposted this week).
Is there expected to be another way to identify if the next connection is a panel or a bridge?

Hi Kieran,
I'm getting started in the DRM subsystem. I couldn't tell if there is a good way to access the panel pointer... I didn't manage to find it, but hopefully someone with more experience can point us to a solution.
Since you mentioned display port, I'm not sure if in your case checking "pdata->next_bridge->type" could be good enough.
Anyway, if this patch causes you problems, please go ahead and ignore it. I'm sure the series you are working on are more important than removing a deprecated function :)
Best wishes, Jose

If it's deprecated, I don't want to block it's removal. Hopefully I can resume my work on this tomorrow so I can check to see what I can parse. Thanks for the lead on the bridge type, I'm sure I've seen that around too so hopefully that's enough. If it is, I'll rebase my work on top of your patch and retest.

Actually, it is. And I think this is actually cleaner (both here, and in the series I'm working on).

So - my series is now working with a bit of adaptation to run on top of your patch, and I think the overall result is better. So:
