Hi Nick and Guenter
Just adding you to this one also seeing as you're looking at that other
sbs_battery patch for me.
Not sure why the get maintainers didn't list you for this one.
Cheers

Add the ability to force load a hot pluggable battery during boot where
there is no gpio detect method available and the module is statically
built. Normal polling will then occur on that battery when it is inserted.

Maybe it is documented in another patch, which I have not seen. If it
isn't, it will have to be documented and reviewed by a devicetree
maintainer. Either case, I don't immediately see why the variable
needs to reside in struct sbs_info; it seems to be used only in the
probe function.
Good point, we don't actually need to store the value, it can just be a
local.
Yep I had done a device tree documentation patch, but confused myself
when submitting due to it having to be in a separate patch
I think I need to create 2 different patches but submit in the same
email via send-patch as a multipart patch..
I'll try to fix that when I send it in again.
