The broadcom-sta driver package is marked as insecure due to CVE-2019-9501
and CVE-2019-9502 (heap buffer overflow vulnerabilities allowing remote code
execution). The driver is also unmaintained and incompatible with modern
Linux kernel security mitigations.
Removed broadcom_sta from extraModulePackages and the corresponding "wl" kernel module.
This resolves test failures where Nixpkgs refuses to evaluate configurations
containing this insecure package.
This does not compile against 6.x Kernel.
This is also no longer necessary for 6.x Kernel.
One can use "acpi_video0" device instead of "mba6x_backlight" device.
