There are indeed cases where a BE takes incompatible hw configuration, which needs be_hw_params_fixup. But, in general, the FE's hw_params is just copied to BE. That is, we assume here blindly that FE's configuration is compatible with BE's. And, now this assumption isn't true in rcar's case, so we face the issue.
Well, it's as much that we're assuming there's rewriting going on which handles things - in many of these systems everything will be going through a DSP which rewrites everything on the way.
