Re: [PATCH v2] console: Don't prefer first registered if DT specifies stdout-path

Fix this by not automatically preferring the first registered console if
one is specified by the device tree. This allows consoles to be
registered but not enabled, and once the driver for the console selected
by stdout-path calls of_console_check() the driver will be added to the
list of preferred consoles before any other console has been enabled.
When that console is then registered via register_console() it will be
enabled as expected.

This breaks the console on PowerMac.  There is no output and it panics
eventually.

Hi Andreas,

Could you share the device tree from your system?

Thanks,
