The maintainer Hemanth seems to have disappeared. Let's ask some of the OMAP and ex-OMAP people, I think they know or know who knows... Tony, Peter, Paul: drivers/misc/bh1780gli.c has a funky sysfs ABI. It is only used in arch/arm/boot/dts/omap4-sdp.dts as far as I can tell. What device is this, and more importantly, who is running it and with what userspace? I'm happy to go and patch that userspace if I can just get a pointer to whoever is developing it. Sailfish?
