Do you want us to add platform device from another driver which is 
probed only on Qualcomm devices (like socinfo from previous discussion) 
and get rid of the module init function entirely? As keeping anything in 
the module init will get it executed on all platforms.


With this patch version, we have tried to reduce the code execution on 
non-Qualcomm devices (also tried the alternative as mentioned in the 
cover letter). Adding platform device from another driver as described 
above would eliminate it entirely, please let us know if you want us to 
do that.


Thanks,
