Thanks for the reply.

In fact, I find that a function possibly-related to this function pointer can sleep:
drivers/hid/intel-ish-hid/ishtp-hid.c, 97: kzalloc(GFP_KERNEL) in ishtp_hid_request
But I am not quite sure whether this function is really referenced by the function pointer, so I did not report it.
Best wishes, Jia-Ju Bai
