Hey Krzysztof,

JFYI, I think there was some discussion on IRC (specifically #linux-msm) 
about having the feature bit dependency back in February.

I believe both Abhinav and Dmitry agreed that you can keep the changes 
to do version checks and drop this dependency.

There are still some ongoing discussions regarding the feature bit 
series, so this way your series isn't blocked by that.

Thanks,

Jessica Zhang
