From 92f1e9a4b31c0bf0f4f61ab823a6a88657323646 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 13 May 2021 19:39:31 -0600 Subject: [PATCH] clk: Detect failure to set defaults When the default clocks cannot be set, the clock is silently probed and the error is ignored. This is incorrect, since having the clocks at the correct speed may be important for operation of the system. Fix it by checking the return code.
