Input: keyspan_remote - replace GFP_ATOMIC with GFP_KERNEL in keyspan_probe()
keyspan_probe() is never called in atomic context. It calls usb_alloc_coherent() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
