From a9a1f9c315c27fe7a260cd453167981cd680dae8 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 6 Jan 2010 23:51:47 -0800 Subject: [PATCH] Input: atkbd - switch to dev_err() and friends dev_err(), dev_warn() and dev_dbg() ensure consistency in driver messages. Also switch to using bool where appropriate and fix some formatting issues.
