From a058be68bd962842dda7862e80ca18806df8cb2d Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 5 Apr 2013 16:12:10 -0700 Subject: [PATCH] staging: comedi: serial2002: rename all the static functions Many of the static functions in this driver have names that could potentially clash with external symbols (tty_ioctl, tty_write, etc.). Rename all the static functions so they have a 'serial2002_' prefix to avoid any issues.
