I'm guessing "1dfef20a4cf82997d4c7520138ed8188a181241c" is the commit id.
Subject is: "brcmsmac: remove PCI_FORCEHT() macro"
The BCM4716 is a SoC and does not have a PCI client interface, so this
condition is never true.

I'm guessing the piece of code is invoked on all flavors of bcm471,
so while it doesn't get invoked on most devices, some of them it
definitely can be.

I'm not actually. Currently exploring a device with ASUS's minimal shell
they give you. According to /proc/cpuinfo, "system type: Broadcom
BCM4716 chip rev 1 pkg 10". If I'm looking at the correct byte in
/sys/devices/[...]/config, it does in fact appear to be 0x0A (decimal
I've seen photos of some people in Taiwan who soldered something at V11
(presumably a voltage regulator, it's all Chinese to me). I'm guessing
they did in fact get a MiniPCIe card to work, but everything is in the
wrong language. :-) The crucial build photo of the regulator module
has disappeared, so it is more difficult to reconstruct.
