From 53288fe9bdc7e8a0265bbe9074f71f1a6c478008 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 12 Sep 2014 15:11:56 +0300 Subject: [PATCH] spi: dw: don't use mrst prefix anymore Since driver is used on other platforms and debugfs stuff would be useful there as well let's substitute mrst_ by dw_ where it suits. Additionally let's use SPI master device name when print registers dump.
