I see that in drivers/base/firmware_loader/main.c but the warning is
complaining about drivers/base/firmware_loader/builtin/main.c, where I
only see

#include <linux/firmware.h>

Sorry for the issues with reproducing. For what it's worth, I can
reproduce this locally and adding

#include "../firmware.h"

to drivers/base/firmware_loader/builtin/main.c fixes it for me.

Cheers,
Nathan
