Hi Jeff,

I thought so too. This is to fix below warnings seen when building MHI 
as a MODULE:

WARNING: modpost: missing MODULE_LICENSE() in 
drivers/bus/mhi/core/main.o
WARNING: modpost: missing MODULE_LICENSE() in drivers/bus/mhi/core/pm.o
WARNING: modpost: missing MODULE_LICENSE() in 
drivers/bus/mhi/core/boot.o

We've only had those in init.c so far.

Thanks,
Bhaumik
