ALSA: aloop - add locking to timer access

2012-10-12T20:50:26+00:00

commit d4f1e48bd11e3df6a26811f7a1f06c4225d92f7d upstream.

When the loopback timer handler is running, calling del_timer() (for STOP
trigger) will not wait for the handler to complete before deactivating the
timer. The timer gets rescheduled in the handler as usual. Then a subsequent
START trigger will try to start the timer using add_timer() with a timer pending
leading to a kernel panic.

Serialize the calls to add_timer() and del_timer() using a spin lock to avoid
this.

ALSA: platform: Check CONFIG_PM_SLEEP instead of CONFIG_PM

2012-08-09T13:47:15+00:00

When CONFIG_PM is set but CONFIG_PM_SLEEP is unset,
SIMPLE_DEV_PM_OPS() ignores the given functions, and this leads to
compile warnings.

For avoiding this, simply check CONFIG_PM_SLEEP instead of CONFIG_PM.

ALSA: mpu401: Fix missing initialization of irq field

2012-07-25T12:04:04+00:00

The irq field of struct snd_mpu401 is supposed to be initialized to -1.
Since it's set to zero as of now, a probing error before the irq
installation results in a kernel warning "Trying to free already-free
IRQ 0".

ALSA: Convert to new pm_ops for PCI drivers

2012-07-03T06:23:03+00:00

Straightforward conversion to the new pm_ops from the legacy
suspend/resume ops.

Since we change vx222, vx_core and vxpocket have to be converted,
too.

ALSA: snd-aloop - improve the sample copy accurracy

2012-05-15T06:34:38+00:00

Maintain both streams (playback, capture) synchronized. Previous code
didn't take in account the small byte count drifts caused by the irq
position rounding.

Documentation: remove references to /etc/modprobe.conf

2012-03-30T23:03:15+00:00

Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
is no longer parsed by new kmod tool. References to this file are
replaced in Documentation, comments and Kconfig according to the
context.

There are also some references to the old /etc/modules.conf from 2.4
kernels that are being removed.

ALSA: module_param: make bool parameters really bool

2011-12-19T09:34:41+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

ALSA: convert sound/* to use module_platform_driver()

2011-11-27T17:43:48+00:00

This patch converts the drivers in sound/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.
