[PATCH v6 47/52] PM / devfreq: tegra20: Silence deferred probe error

From: Dmitry Osipenko
Date: Sun Oct 25 2020 - 18:19:21 EST


Tegra EMC driver was turned into a regular kernel driver, meaning that it
could be compiled as a loadable kernel module now. Hence EMC clock isn't
guaranteed to be available and clk_get("emc") may return -EPROBE_DEFER.
Let's silence the deferred probe error.
