[PATCH 1/3] tty: xuartps: Fix "may be used uninitialized" build warning

From: Soren Brinkmann
Date: Mon Oct 21 2013 - 19:41:18 EST


Initialize varibles for which a 'may be used uninitalized' warning is
issued.

Signed-off-by: Soren Brinkmann <soren.brinkmann@xxxxxxxxxx>

The warning is actually a false positive. The variables are passed to a
function per reference. That function uses those variables to return
values, which then are used by the caller. Is there a way to
avoid the initialization and the build warning alltogether?
