Subject[PATCH 4.19 127/148] leds: pwm: silently error out on EPROBE_DEFER
Date
4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jerome Brunet <jbrunet@baylibre.com>

commit 9aec30371fb095a0c9415f3f0146ae269c3713d8 upstream.

When probing, if we fail to get the pwm due to probe deferal, we shouldn't
print an error message. Just be silent in this case.
