From 5db496b9c808270e9e569fa721d1ecdd8f145142 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Tue, 24 Feb 2015 14:25:03 -0500 Subject: [PATCH] serial: 8250: Simplify capabilities reset at port unregister Since uart->port.type has just reset to PORT_UNKNOWN, capabilities are reset to uart_config[PORT_UNKNOWN].flags, which is 0. Removes unnecessary dependency on uart_config[].
