------------------------------------------------------
Subject: suspend: make it possible to disable serial console suspend
From: "Rafael J. Wysocki" <rjw@xxxxxxx>
Hack uart_suspend_port() and uart_resume_port() so that serial console
ports are not suspended if CONFIG_DISABLE_CONSOLE_SUSPEND is set.
This makes it possible to debug the suspend and resume routines of all
device drivers as well as the lowest-level swsusp code with the help of the
serial console.
