How is this firmware file loading supposed to work? If I'm reading the
code right, the driver tries to load file "wfm_wf200_??.sec" but in
linux-firmware the file is silabs/wfm_wf200_C0.sec:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/silabs
That can't work automatically, unless I'm missing something of course.
Also I would prefer to use directory name as the driver name wfx, but I
guess silabs is also doable.
Also I'm not seeing the PDS files in linux-firmware. The idea is that
when user installs an upstream kernel and the linux-firmware everything
will work automatically, without any manual file installations.
