Thanks for catching the typo, I will fix it in next patch.

I am not sure if I understood this comment: 1st, ssbi_vib_data.drv_addr 
is defined as a constant value 0x4A, so it would never be 0. 2nd, The 
condition check here is to ignore reading the register base address for 
SSBI_VIB HW, so we should do the check based on the HW type.
