Subject: [PATCH] Revert "serial: 8250: Fix add preferred console for
 serial8250_isa_init_ports()"
MIME-Version: 1.0

This reverts commit 4547cd76f08a6f301f6ad563f5d0e4566924ec6b.

Let's roll back all of the serial core and printk console changes that
went into 6.10-rc1 as there still are problems with them that need to be
sorted out.
