[PATCH 17/39] pcmcia: pcmcia_config_loop() improvement by passing vcc

Dominik Brodowski linux at dominikbrodowski.net
Mon Aug 18 14:53:08 EDT 2008


By passing the current Vcc setting to the pcmcia_config_loop callback
function, we can remove pcmcia_get_configuration_info() calls from many
drivers.
