Thanks for trying the patch. With this patch I was able to boot android13
running 5.15.0-rc4-mainlineon on my Dragonboard 845c with the default
config common/build.config.db845c. Without it it was crashing.
It doesn't solve the firmware loading problem, it just makes it fail
gracefully for the boot to continue. If you share your config I can try
it and see what's wrong.
