Update our copies of the brcm2708 patches to the latest rpi-3.10-y rebased against linux-3.10.y stable (3.10.32). This should hopefully make it easier for us in the future to leverage the raspberry/rpi-* branches. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39770

Subject: [PATCH 146/174] 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.
