Ah, OK.

For now, I would prefer not using it, as I don't want to rebase
on the top of a -rc1 Kernel. I got a breakage on WiFi when
I rebased from 5.7 to 5.8. I would prefer avoiding it just
due to a new printk macro.

Once gets merged, I can post a followup patch replacing the
above by dev_err_probe().

Ok, thanks!

Before posting the big patch series again, let me send the new
version folded into a single patch.

If you'd like to see the entire thing, I'm placing it here:

	https://gitlab.freedesktop.org/mchehab_kernel/hikey-970/-/commits/hikey970_v2/

Except for the Kconfig/Makefile changes (which I folded with the
original patch), the other changes are written as incremental
patches on the top of the previous version.

I also added a fixup patch from John Stultz for adv7511:

	https://gitlab.freedesktop.org/mchehab_kernel/hikey-970/-/commit/81686cb9f01d5c356d67f63eda7a93ec2db5d0f1

With this change, EDID now works fine.

Thanks,
Mauro
