[PATCH AUTOSEL 4.14 081/170] Input: rotary-encoder - don't log EPROBE_DEFER to kernel log

From: Uwe Kleine-König <uwe@kleine-koenig.org>

[ Upstream commit 0832e93632c61987d504e251b927a2be769dd21a ]

When a driver fails to bind because a resource it still missing it's not
helpful to report this as (usually) probing is repeated later.
