From 039ec1f010e6b058f497381d5a6bb840e160b4ac Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Delgado Date: Thu, 6 Nov 2014 09:22:53 +0100 Subject: serial/8250: Remove obsolete handling of rs485 ioctls There is no more users for this functions. All the 8250 drivers are using the rs485 handler on serial_core instead.
