From ad913c11928f51abb6174f165db8d8d205b22e21 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sat, 2 Aug 2008 16:12:00 +0200 Subject: pcmcia: pcmcia_config_loop() improvement by passing vcc By passing the current Vcc setting to the pcmcia_config_loop callback function, we can remove pcmcia_get_configuration_info() calls from many drivers.
