soc: qcom: Make qcom_smem_get() return a pointer Passing a void ** almost always requires a cast at the call site. Instead of littering the code with casts every time this function is called, have qcom_smem_get() return a void pointer to the location of the smem item. This frees the caller from having to cast the pointer.
