ALSA: msnd: Optimize / harden DSP and MIDI loops

2017-09-13T21:09:46+00:00

commit 20e2b791796bd68816fa115f12be5320de2b8021 upstream.

The ISA msnd drivers have loops fetching the ring-buffer head, tail
and size values inside the loops.  Such codes are inefficient and
fragile.

This patch optimizes it, and also adds the sanity check to avoid the
endless loops.

ALSA: Add missing dependency on CONFIG_SND_TIMER

2016-02-17T20:30:58+00:00

commit 61595dca742a9ba9a4c998b9af1f468adc816275 upstream.

Since the build of PCM timer may be disabled via Kconfig now, each
driver that provides a timer interface needs to set CONFIG_SND_TIMER
explicitly.  Otherwise it may get a build error due to missing
symbol.

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: sscape: add missing include of linux/io.h

2015-01-28T15:27:46+00:00

The soundscape driver uses the ISA inb/outb functions declared
in linux/io.h, so it needs to include this header to avoid
a build error:

sscape.c: In function 'sscape_write_unsafe':
sscape.c:203:2: error: implicit declaration of function 'outb' [-Werror=implicit-function-declaration]
