Given that failing to find a DSI host causes the driver to defer probe,
make use of dev_err_probe() to log the reason. This makes the defer
probe reason available and avoids alerting userspace about something
that is not necessarily an error.

With this addressed,
I disagree. That's 87 columns, and the 80-col rule is long gone.
It's still a maintainer's preference. I soft-enforce it in drivers I
maintain. In this case I'll let Neil decide, as he's listed as the
maintainer for drivers/gpu/drm/panel/.
Yes, that's right. Comes down to personal opinion.
Cheers
