How do you think about another wording variant?

   Return values were not checked after calls of the following functions.
   - clk_hw_register_mux
   - clk_hw_register_gate
   - devm_clk_hw_register_clkdev

   * Thus add error detection and the corresponding exception handling.

   * Return the value from the function call “devm_clk_hw_register_clkdev”
     at the end of this function implementation.

Markus
