[OpenWrt-Devel] broadcom-wl @ bcm63xx fails on kernel 4.19

Thu Apr 2 11:59:36 EDT 2020

Hi again,

it looks like the problem is only the broadcom-wl package, which is pulled via DEVICE_PACKAGES on the following devices:
actiontec_r1000h
tecom_gw6000
tecom_gw6200

If the package is removed, target seems to build fine on 4.19.

So, how to proceed here? 

Best

Adrian
