Subject: [PATCH 4.14 096/193] ASoC: sun8i-codec: Invert Master / Slave condition

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maxime Ripard <maxime.ripard@...e-electrons.com>

commit 560bfe774f058e97596f30ff71cffdac52b72914 upstream.

The current code had the condition backward when checking if the codec
should be running in slave or master mode.

Fix it, and make the comment a bit more readable.
