Hi,

I'm using busybox 1.32. I've compiled 5.7 kernel in my ubuntu 20.04
development system.
When booting ubuntu, every kernel module is OK, but when booting busybox,
in every module which needs firmware, loading firmware fails with following
message:

[    8.755012] platform regulatory.0: Direct firmware load for
regulatory.db failed with error -2
[   12.543489] r8169 0000:04:00.0: Direct firmware load for
rtl_nic/rtl8168e-3.fw failed with error -2
[   12.543494] r8169 0000:04:00.0: Unable to load firmware
rtl_nic/rtl8168e-3.fw (-2)

[  125.508623] si2168 4-0064: Direct firmware load for
dvb-demod-si2168-b40-01.fw failed with error -2

I've copied all firmware files in /lib/firmware. Also firmware load fails
both in boot, and after boot when a hardware needs to load firmware.

It seems it is something related to 5.x kernel with busybox, because I've
not noticed similar behavior in 4.9 kernel, which I used before.

Any suggestions? I'm really stock with this!
