pcistub_probe() is never called in atomic context. This function is only set as ".probe" in struct pci_driver. Despite never getting called from atomic context, pcistub_probe() calls kmalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by: Jia-Ju Bai <baijiaju1...@gmail.com>
