Subject: [PATCH 1/2] ASoC: fsl_ssi: AC'97 ops need regmap, clock and cleaning up on failure
Date: Mon, 20 Nov 2017 23:14:55 +0100 [thread overview]
Message-ID: <ecfcedaa-f0e9-ec1f-82c5-f0d319068a5d@maciej.szmigiero.name> (raw)
AC'97 ops (register read / write) need SSI regmap and clock, so they have
to be set after them.
We also need to set these ops back to NULL if we fail the probe.
