From 43a354a21a6a21f050b95317148661a465108cba Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 17 Oct 2023 17:06:53 +0300 Subject: [PATCH] clk: at91: remove unnecessary conditions This code checks "if (parent_hw)" is non-NULL, but then it has more checks if parent_hw is non-NULL on the lines inside the if statement. It is a bit confusing. For the else statement, keep in mind that at the start of the function we checked: if (!(parent_name || parent_hw)) return ERR_PTR(-EINVAL); That check ensures that if parent_hw is NULL that means that parent_name is non-NULL. At least one must always be non-NULL. So here again, the checks inside the if statement can be removed. In the original code, it was a bit confusing and you could easily get the impression that "init.num_parents" could be zero. When we remove the unnecessary checking it's more obvious that it's always set to 1.
