clk: clk-conf: Do not print error messages if EPROBE_DEFER (e2d79333) · Commits · 戴 / test

EPROBE_DEFER is not an error, hence printing an error message like clk: couldn't get clock 0 for /soc/display@feb00000 may confuse the user. Suppress error messages in case of probe deferral to fix this. Signed-off-by:
