Re: [PATCH v2 1/2] ASoC: fsl_mqs: Don't check clock is NULL before calling clk API

    clk_prepare_enable and clk_disable_unprepare check the input
    clock parameter in the beginning of the function,

These functions call further functions which perform null pointer checks.

                                                      if the parameter
    is NULL, clk_prepare_enable and clk_disable_unprepare will
    return immediately.

The interpretation of these function implementations seems to be reasonable.
Would you like to achieve any improvements for the corresponding software documentation?

    So Don't need to check input clock parameters before calling clk API.

What do you find imperative in this wording?

Another wording alternative:
   Thus omit extra null pointer checks before four function calls.

Markus
