From ac48653cec7dd9a5606a7057413a880d6880d5d3 Mon Sep 17 00:00:00 2001 From: Roger Tseng Date: Mon, 4 Feb 2013 15:45:57 +0800 Subject: [PATCH] mmc: rtsx: remove driving adjustment Several new models of readers use different way to select driving capability (a necessary adjustment along with voltage change). Removing this from device-independent rtsx_pci_sdmmc module. It will be implemented in device-depend calls encapsulated by rtsx_pci_switch_output_voltage().
