From bd86ef378412fc30282daf722a833f734e4e2236 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Fri, 3 Apr 2009 15:48:44 -0500 Subject: [PATCH] cpm_uart: Initialize port.dev before it's used. Previously, this caused NULL to sometimes be passed as a device to the DMA code. With recent DMA changes, that now causes a BUG().
