Hmm, how is rc-cec supposed to be loaded?

At boot, I see:

[   16.577704] IR keymap rc-cec not found
[   16.586675] Registered IR keymap rc-empty
[   16.591668] input: RC for dw_hdmi as /devices/soc0/soc/120000.hdmi/rc/rc1/input3
[   16.597769] rc1: RC for dw_hdmi as /devices/soc0/soc/120000.hdmi/rc/rc1

Yet the rc-cec is a module in the filesystem, but it doesn't seem to
be loaded automatically - even after the system has booted, the module
hasn't been loaded.

It looks like it _should_ be loaded, but this plainly isn't working:

        map = seek_rc_map(name);
#ifdef MODULE
        if (!map) {
                int rc = request_module("%s", name);
                if (rc < 0) {
                        printk(KERN_ERR "Couldn't load IR keymap %s\n", name);
                        return NULL;
                }
                msleep(20);     /* Give some time for IR to register */

                map = seek_rc_map(name);
        }
#endif
        if (!map) {
                printk(KERN_ERR "IR keymap %s not found\n", name);
                return NULL;
        }

Any ideas?
