pcan_add_channels() is never called in atomic context. pcan_add_channels() is only called by pcan_probe(), which is only set as ".probe" in struct pcmcia_driver. Despite never getting called from atomic context, pcan_add_channels() calls mdelay() to busily wait. This is not necessary and can be replaced with usleep_range() to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
