From ae6eba84efd2ccc214ed50e8b35bbc54cb50121b Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 2 Jul 2012 15:47:47 -0700 Subject: [PATCH] staging: comedi: das08_cs: refactor the pcmcia probe/remove Move the pcmcia_disable_device() call where needed in the pcmcia probe/remove and delete the das08_pcmcia_release() function. Move the logic of the das08_pcmcia_config() directly into the probe function and properly return an error code when the config fails. Only set cur_dev, used by the comedi_driver, if the pcmcia probe is successful. Also, make sure to NULL it in the remove. Remove all the kernel messages in the pcmcia support code. They are just added noise.
