savage_init_hw() is never called in atomic context. The call chains ending up at savage_init_hw() are: [1] savage_init_hw() <- savagefb_probe() [2] savage_init_hw() <- savagefb_resume() savagefb_probe() is only set as ".probe" in struct pci_driver. savagefb_resume) is only set as ".resume" in struct pci_driver. These functions are not called in atomic context. Despite never getting called from atomic context, savage_init_hw() 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.
