ALSA: aloop - add locking to timer access

2012-10-12T20:38:51+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: mpu401: Fix missing initialization of irq field

2012-08-09T15:31:52+00:00

commit bc733d495267a23ef8660220d696c6e549ce30b3 upstream.

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".

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.

sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed

2011-10-31T23:31:22+00:00

These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition.  Previously,
they got it via the implicit module.h inclusion.

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21+00:00

Lots of sound drivers were getting module.h via the implicit presence
of it in  but we are going to clean that up.  So
fix up those users now.

sound: fix drivers needing module.h not moduleparam.h

2011-10-31T23:31:19+00:00

The implicit presence of module.h lured several users into
incorrectly thinking that they only needed/used modparam.h
but once we clean up the module.h presence, these will show
up as build failures, so fix 'em now.

ALSA: aloop - Use vmalloc buffer

2011-09-24T10:16:29+00:00

snd-aloop driver is virtual and has no need for allocating contiguous
pages.  It'll be more system-friendly to use vmalloc buffers.
