Subject: [PATCH 5/7] serial: remove back and forth conversions in serial_out_sync
Date: Thu,  1 Mar 2012 21:33:21 -0500	[thread overview]
Message-ID: <1330655603-5268-6-git-send-email-paul.gortmaker@windriver.com> (raw)
In-Reply-To: <1330655603-5268-1-git-send-email-paul.gortmaker@windriver.com>

The two callers to serial_out_sync() have a struct port right
there in scope, but then pass in a struct 8250_port which then
is locally resolved to a struct port.

Delete the needless back and forth and just pass in the struct
port directly.
