Subject: [PATCH] Tentative fix for broadcom-wl 6.30.223.271 driver for Linux 5.17-rc1
|
|
|
|
Set netdev->dev_addr through dev_addr_mod + PDE_DATA fix
|
|
|
|
Since Linux 5.17 netdev->dev_addr is const and must be changed through
|
|
dev_addr_mod, otherwise a warning is logged in dmesg and bad things may happen.
|
|
|
|
NB: The #if is not wrong, dev_addr_mod is defined since Linux 5.15-rc1
|
|
|
|
Plus a trivial fix for PDE_DATA.
|
|
|
|
Applies on top of all the patches applied to broadcom-wl-dkms 6.30.223.271-28 on Arch Linux.
