The current implementation has abstractions that don't give any benefits. The print_fn callback (and its only callback implementation, ufs_qcom_dump_regs_wrapper()) was only used by ufs_qcom_print_hw_debug_reg_all() and just multiplies len by 4 before calling ufshcd_dump_regs(). ufs_qcom_print_hw_debug_reg_all() is only called by ufs_qcom_dump_dbg_regs(). There's no real gain in those abstractions, so let's just do the work directly in ufs_qcom_dump_dbg_regs() (the dbg_register_dump callback).
