staging: comedi: cb_das16_cs: refactor the pcmcia attach/detach
Move the pcmcia_disable_device() call where needed in the pcmcia attach/detach and delete the das16cs_pcmcia_release() function. Move the logic of das16cs_pcmcia_config() directly into the attach function and properly return an error code when the config fails. Only set the cur_dev, used by the comedi_driver, if the pcmcia attach is successful. Also, make sure to NULL it in the detach. Remove all the kernel messages in the pcmcia support code. They are just added noise.
