[PATCH AUTOSEL 4.14 66/95] leds: pwm: silently error out on EPROBE_DEFER

[Sasha Levin]

From: Jerome Brunet <jbrunet@xxxxxxxxxxxx>

[ Upstream commit 9aec30371fb095a0c9415f3f0146ae269c3713d8 ]

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.
