[PATCH 1/3] ASoC: tegra: use DAI's not card's dev for dev_err
From: Stephen Warren <hidden>
Date: 2012-06-06 23:15:05
Subsystem:
sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers:

From: Stephen Warren <redacted> This is the actual device of the I2S or SPDIF controller reporting the problem. If a future change converts these controllers to be CODECs, then there may be no pcm associated with the substream, so this change avoids a crash.
