From: Simon Glass Date: Wed, 24 Mar 2021 21:26:09 +0000 (+1300) Subject: clk: Return -ENOSYS when system call is not available X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=3bc11b983d01e8b761cfeafa60d520b5702f7d10;p=u-boot.git 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.
