[alsa-devel] [PATCH v2] pinctrl: madera: Fix uninitialized variable bug in madera_mux_set_mux
by Gustavo A. R. Silva 12 Oct '18

There is a potential execution path in which variable *ret* is checked in an IF statement, and then its value is used to report an error at line 659 without being properly initialized previously: 659 if (ret) 660 dev_err(priv->dev, "Failed to write to 0x%x (%d)\n", reg, ret); Fix this by initializing variable *ret* to 0 in order to avoid unpredictable or unintended results.

[alsa-devel] Oops when unloading SOF driver modules
by Guennadi Liakhovetski 11 Oct '18

11 Oct '18

Hi, I'm tracking down a kernel Oops, occurring when unloading driver modules. A complete Oops is below. It triggers because cpu_dai->driver is NULL after remove_dai() in soc-topology.c freed it. On my Debian system this only happens when I unload modules directly after loading. If some time passes after loading the drivers, pulseaudio completes its probing and releases the hardware, then remove_dai() isn't called before snd_pcm_do_stop() but after, then everything is running correctly. I'm not sure what the best way to fix this would be. Any ideas?
