I'm actually fine with this approach.  Patch has been applied.  I did a trivial 
style fix afterward to keep the line length less than 80 characters.

Huawei uses Qualcomm chips in their devices and thus share the same 'quirks'.  
I expect the vendor.h quirks to get refined over time anyway, so for now it is 
fine to leave it the way it is.
