Subject: Input: rotary-encoder - don't log EPROBE_DEFER to kernel log
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0832e93632c61987d504e251b927a2be769dd21a;p=linux.git

Input: rotary-encoder - don't log EPROBE_DEFER to kernel log

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.
