+Check if alloc_percpu returns NULL. Because we can readily catch and

+This was found by syzkaller both on x86 and powerpc, and the reproducer

+There's a syz reproducer on the powerpc syzbot that eventually hits
+the bug, but it can take up to an hour or so before it keels over on a
+kernel with all the syzkaller debugging on, and even longer on a
+production kernel. I have been able to reproduce it once on a stock
+Ubuntu 5.0 ppc64le kernel.
+
+I will ask MITRE for a CVE - while only the process doing the syscall
+gets killed, it gets killed while holding the relay_channels_mutex,
+so it blocks all future relay activity.

+Subject: HID: Fix assumption that devices have inputs
+
+The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff
+driver. The problem is caused by the driver's assumption that the
+device must have an input report. While this will be true for all
+normal HID input devices, a suitably malicious device can violate the
+assumption.
+
+The same assumption is present in over a dozen other HID drivers.
+This patch fixes them by checking that the list of hid_inputs for the
+hid_device is nonempty before allowing it to be used.
