ALSA: seq: Fix missing error handling in snd_seq_timer_open()

2013-03-20T20:10:54+00:00

commit 66efdc71d95887b652a742a5dae51fa834d71465 upstream.

snd_seq_timer_open() didn't catch the whole error path but let through
if the timer id is a slave.  This may lead to Oops by accessing the
uninitialized pointer.

ALSA: vmaster: Fix slave change notification

2013-03-14T18:26:24+00:00

commit 2069d483b39a603a5f3428a19d3b4ac89aa97f48 upstream.

When a value of a vmaster slave control is changed, the ctl change
notification is sometimes ignored.  This happens when the master
control overrides, e.g. when the corresponding master control is
muted.  The reason is that slave_put() returns the value of the actual
slave put callback, and it doesn't reflect the virtual slave value
change.

This patch fixes the function just to return 1 whenever a slave value
is changed.

ALSA: hda - hdmi: Make jacks phantom, if they're not detectable

2013-03-03T22:03:31+00:00

commit 30efd8debd1ef30be342d374f01e993509f5b76b upstream.

Just as for analog codecs, a jack that isn't suitable for detection
(in this case, NO_PRESENCE was set) should be a phantom Jack
instead of a normal one.

Thanks to Raymond Yau for spotting.

ALSA: bt87x: Make load_all parameter working again

commit aacfddfdadb3540651d263245069631f341e953a upstream.

Along with a clean up commit [e9f66d9b9: ALSA: pci: clean up using
module_pci_driver()], bt87x driver lost the functionality of load_all
parameter.  This patch does a partial revert of the commit only for
bt87x.c to recover it.

ASoC: arizona: Fixed a bug in FLL fractional calculation

2013-02-28T13:38:37+00:00

commit 01f58153aefc158fd690b337d29ad140e963959d upstream.

Previously arizona_calc_fll() was checking if the target frequency is
exactly divisible by reference frequency, but should have been product
of the ratio and the reference frequency.

Also scale down the Lamba and Theta coefficients be under 16-bits in
order to match the registers.

commit bbfd8a19b6913f50a362457c34d49bfafe5e456e upstream.

Currently, eld_valid is never set to false, except at kernel module
load time. This patch makes sure that eld is no longer valid when
the cable is (hot-)unplugged.
