ASoC: dapm: Fix potential DAI widget pointer deref when linking DAIs

2018-10-04T00:01:48+00:00

[ Upstream commit e01b4f624278d5efe5fb5da585ca371947b16680 ]

Sometime a component or topology may configure a DAI widget with no
private data leading to a dev_dbg() dereferencne of this data.

Fix this to check for non NULL private data and let users know if widget
is missing DAI.

ALSA: snd-aoa: add of_node_put() in error path

2018-10-04T00:01:45+00:00

[ Upstream commit 222bce5eb88d1af656419db04bcd84b2419fb900 ]

 Both calls to of_find_node_by_name() and of_get_next_child() return a
node pointer with refcount incremented thus it must be explicidly
decremented here after the last usage. As we are assured to have a
refcounted  np  either from the initial
of_find_node_by_name(NULL, name); or from the of_get_next_child(gpio, np)
in the while loop if we reached the error code path below, an
x of_node_put(np) is needed.

ALSA: oxfw: fix memory leak of private data

2018-09-29T10:07:32+00:00

commit 498fe23aad8e3b5a9554f55719c537603b4476ea upstream.

Although private data of sound card instance is usually allocated in the
tail of the instance, drivers in ALSA firewire stack allocate the private
data before allocating the instance. In this case, the private data
should be released explicitly at .private_free callback of the instance.

This commit fixes memory leak following to the above design.

ALSA: emu10k1: fix possible info leak to userspace on SNDRV_EMU10K1_IOCTL_INFO

2018-09-29T10:07:30+00:00

commit 49434c6c575d2008c0abbc93e615019f39e01252 upstream.

snd_emu10k1_fx8010_ioctl(SNDRV_EMU10K1_IOCTL_INFO) allocates
memory using kmalloc() and partially fills it by calling
snd_emu10k1_fx8010_info() before returning the resulting
structure to userspace, leaving uninitialized holes. Let's
just use kzalloc() here.
