Issue/Bug Description: Bonobo model bonx6 keyboard LEDs get turned off at boot time and don't work thereafter.

Steps to reproduce (if you know): After power on, up to the time where I'm prompted for the disk decryption key all the kb led functions work fine (Fn + numpad / or * or - or +). As bootup proceeds however, the kb leds get turned off in conjunction with display of the following log messages:

Aug 31 09:36:46 dll76b kernel: [    9.822560] system76: loading out-of-tree module taints kernel.

Once fully booted and logged in, the kb led fn keys * - and + elicit a pop up window with an icon identifying the intended function but have no effect on the actual kb leds. The following messages are simultaneously logged to /var/log/kern.log:

fn * off then on:

fn - - then fn + +:

Aug 31 10:12:09 dll76b kernel: [ 2142.458960] system76: kb_led_set 255

The fn / function doesn't do anything (no log message and no popup window).

Expected behavior: Expect the kb led fn keys to work properly after pop_os has booted.
