From d3045184699d6220e5c03c2d6b1dfc449c3b873e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 14 Jul 2026 18:50:18 +0300 Subject: [PATCH] clk: document that clk_get_parent() returns NULL The documentation in the clk.h file says that clk_get_parent() returns error pointers but it doesn't. It's also not consistent with the comments next to the clk_get_parent() implementation which say that it returns NULL when the clk is NULL. Update the comments so they are consistent and accurate and say that it returns NULL.
