isp1760_init_core() is never called in atomic context. The call chains ending up at isp1760_init_core() are: [1] isp1760_init_core() <- isp1760_register() <- isp1760_plat_probe() [2] isp1760_init_core() <- isp1760_register() <- isp1761_pci_probe() isp1760_plat_probe() is set as ".probe" in struct platform_driver. isp1761_pci_probe() is set as ".probe" in struct pci_driver. These functions are not called in atomic context. Despite never getting called from atomic context, isp1761_pci_probe() calls mdelay() to busily wait. This is not necessary and can be replaced with msleep() to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
