------------------------------------------------------
Subject: newport_con: Fix resource acquisition
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
newport_con can be compiled statically and assigned directly to conswitchp,
or it can be compiled as a module, in which case, it goes through the
take_over_console() pathway.
In the former, resource acquisition is done in newport_startup() and in the
latter, the resources are acquired in newport_console_init().
Fix so resources are properly acquired whatever pathway it goes through.
