Subject: [PATCH 146/196] fixes a bug in the snd-bcm2835 driver
|
|
|
|
The "instance" field of bcm2835_alsa_stream_t may be accessed uninitialized
|
|
by bcm2835_audio_set_ctls_chan if called during stream creation. This fix
|
|
deferres the addition to of the stream to chip untill it has been fully
|
|
initialized.
