ALSA: seq: Drop snd_seq_autoload_lock() and _unlock()

2015-02-12T13:42:31+00:00

The autoload lock became already superfluous due to the recent rework
of autoload code.  Let's drop them now.  This allows us to simplify a
few codes nicely.

ALSA: seq: Define driver object in each driver

2015-02-12T13:15:54+00:00

This patch moves the driver object initialization and allocation to
each driver's module init/exit code like other normal drivers.  The
snd_seq_driver struct is now published in seq_device.h, and each
driver is responsible to define it with proper driver attributes
(name, probe and remove) with snd_seq_driver specific attributes as id
and argsize fields.  The helper functions snd_seq_driver_register(),
snd_seq_driver_unregister() and module_snd_seq_driver() are used for
simplifying codes.

ALSA: seq: Deletion of unnecessary checks before the function call "snd_midi_event_free"

2015-01-04T14:11:05+00:00

The snd_midi_event_free() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

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.

sound: rawmidi: disable active-sensing-on-close by default

2009-07-15T09:57:20+00:00

Sending an Active Sensing message when closing a port can interfere with
the following data if the port is reopened and a note-on is sent before
the device's timeout has elapsed.  Therefore, it is better to disable
this setting by default.

sound: seq_midi: do not send MIDI reset when closing

2009-07-15T09:56:58+00:00

Sending a MIDI reset message when closing a port is wrong because we
only want to shut the device up, not to reset all settings.
Furthermore, many devices ignore this message.

Fortunately, the RawMIDI layer already shuts the device up, so we can
ignore this matter here.

seq-midi: always log message on output overrun

2009-07-15T09:56:06+00:00

It turns out that the main cause of output buffer overruns is not slow
drivers but applications that generate too many messages.  Therefore, it
makes more sense to make that error message always visible, and to
rate-limit it.

ALSA: Kill snd_assert() in sound/core/*

Kill snd_assert() in sound/core/*, either removed or replaced with
if () with snd_BUG_ON().
