Subject: [PATCH v2 4/4] HID: bpf: doc fixes for hid_hw_request() hooks

We had the following errors while doing make htmldocs:

Documentation/hid/hid-bpf:185: include/linux/hid_bpf.h:167:
	ERROR: Unexpected indentation.

Also ensure consistency with the rest of the __u64 vs u64.

Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>
Fixes: 9286675a2aed ("HID: bpf: add HID-BPF hooks for hid_hw_output_report")
Signed-off-by: Benjamin Tissoires <bentiss@...nel.org>
