-Subject: [PATCH] clk: Fix clk_get_parent() documentation
-
-The clk_get_parent() documentation in the header states that it will
-return a valid pointer, or an error pointer on failure.
-
-However, the documentation in the source file, and the code itself, will
-return also return NULL if there isn't any parent for that clock. Let's
-mention it.
-
-An orphan clock should return NULL too, so let's add a test for it.
