[PATCH] HID: bpf: fix hid_bpf_input_report() when hid-core is not ready
From: Benjamin Tissoires
Date: Thu Apr 11 2024 - 03:06:12 EST
Reported by linux-next:
After merging the hid tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
x86_64-linux-gnu-ld: vmlinux.o: in function `hid_bpf_input_report':
(.text+0x1c75181): undefined reference to `hid_input_report'
Caused by commit 9be50ac30a83 ("HID: bpf: allow to inject HID event
from BPF")
I just forgot to put the indirection in place.

Seems like an overlook in my patch.
