Hi!
After kernel 4.17 the dtb for raspberry pi 3 b is not ok and thus the wifi
is not found and cannot be used.
Looking at the differences from 4.17 to 4.18 I have discovered that if you
revert this single patch affecting only the pi3b model the wifi is
discovered and works again.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/bcm2837-rpi-3-b.dts?id=b1b8f45b3130dbd8704e5ea0d82b49b1d929498e
I have tested this both on Linus kernel 4.20-rc5 and on Debian 4.19.5 as
currently on experimental, on both reverting this patch makes the wifi work
again.
Regards
