From cc020ea404cd73d8eb579d592211c7fd2972ef0f Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Sat, 11 Apr 2015 15:56:01 +0200 Subject: [PATCH] drivers/tty/serial/crisv10.c: remove dead #ifdef blocks ETRAX_RS485_{ON_PORT_G, LTC1387} are not defined in Kconfig. The affected #ifdef block have not been compiled for years, so remove them entirely.
