[PATCH] pcmcia: add return value to _config() functions
Most of the driver initialization isn't done in the .probe function, but in the internal _config() functions. Make them return a value, so that .probe can properly report whether the probing of the device succeeded or not. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
