doc_probe() is never called in atomic context. doc_probe() is only called by init_nanddoc(), which is only set as a parameter of module_init(). This function is not called in atomic context. Despite never getting called from atomic context, doc_probe() 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.
