Hi Georgi,

Thanks for the patch. I have a question about these compatible strings:

I checked the mainline kernel source, but these names are not found
in the DTS files under arch/arm/boot/dts/marvell/. Instead, mainline uses
"linksys,rango" and "linksys,venom".

As a result, this machine check will always fail on a pure mainline kernel,
making the quirk ineffective.
