10   This function works pretty much like <code class="function">request_firmware</code>, but this doesn't
11   fall back to usermode helper even if the firmware couldn't be loaded
12   directly from fs.  Hence it's useful for loading optional firmwares, which
13   aren't always present, without extra long timeouts of udev.
