From 3bc11b983d01e8b761cfeafa60d520b5702f7d10 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 25 Mar 2021 10:26:09 +1300 Subject: [PATCH] clk: Return -ENOSYS when system call is not available Update clk_composite_set_parent() to use -ENOSYS, which is the correct error code for U-Boot. Also rearrange the code so that the error condition is clearly indicated and the function runs to the end in the normal case, since this is the common style in U-Boot.
