Subject: ASoC: simple-card: un-implemented set_fmt is not error
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e244bb9bc1883547d44642c99f483c2e57e2a940;p=deliverable%2Flinux.git

ASoC: simple-card: un-implemented set_fmt is not error

Current simple-card returns error if DAI doesn't
support .set_fmt callback.
But the error is -ENOTSUPP (= not supported),
and it is not error.
This patch avoids such case
