From f6a4f0b424df957d84fa7b9f2d02981234ff5828 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 29 Jul 2021 15:27:03 +0300 Subject: m68k: coldfire: return success for clk_enable(NULL) The clk_enable is supposed work when CONFIG_HAVE_CLK is false, but it returns -EINVAL. That means some drivers fail during probe. [ 1.680000] flexcan: probe of flexcan.0 failed with error -22 Fixes: c1fb1bf64bb6 ("m68k: let clk_enable() return immediately if clk is NULL") Fixes: bea8bcb12da0 ("m68knommu: Add support for the Coldfire m5441x.")
