Subject: [PATCH] pwm: silently error on EPROBE_DEFER
Date: Tue, 23 May 2017 18:05:03 +0200 [thread overview]
Message-ID: <20170523160503.16920-1-jbrunet@baylibre.com> (raw)
In of_pwm_chip, if we fail to get the pwm chip due to probe defer, we
shouldn't print an error message. Just be silent in this case.
