From: Dominik Brodowski Date: Sun, 18 Oct 2009 16:28:39 +0000 (+0200) Subject: pcmcia: use pcmcia_loop_config in misc pcmcia drivers X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aaa8cfdada648a6bae32f62df76cc60137a2b323;p=mv-sheeva.git pcmcia: use pcmcia_loop_config in misc pcmcia drivers Use pcmcia_loop_config() in a few drivers missed during the first round. On fmvj18x_cs.c it -- strangely -- only requries us to set conf.ConfigIndex, which is done by the core, so include an empty loop function which returns 0 unconditionally. CC: David S.
