|
|
*
|
|
|
|
* Dec. 19, 2002 Takashi Iwai <tiwai@suse.de>
|
|
|
|
* - use the DSX channels for the first pcm playback.
|
|
|
|
* (on VIA8233, 8233C and 8235 only)
|
|
|
|
* this will allow you play simultaneously up to 4 streams.
|
|
|
|
* multi-channel playback is assigned to the second device
|
|
|
|
* on these chips.
|
|
|
|
* - support the secondary capture (on VIA8233/C,8235)
|
|
|
|
* - SPDIF support
|
|
|
|
* the DSX3 channel can be used for SPDIF output.
|
|
|
|
* on VIA8233A, this channel is assigned to the second pcm
|
|
|
|
* playback.
|
|
|
|
* the card config of alsa-lib will assign the correct
|
|
|
|
* device for applications.
|
|
|
|
* - clean up the code, separate low-level initialization
|
|
|
|
* routines for each chipset.

[ALSA] Remove redundant NULL checks before kfree

Checking a pointer for NULL before calling kfree() on it is redundant,
kfree() deals with NULL pointers just fine.
This patch removes such checks from sound/
This patch also makes another, but closely related, change.
It avoids casting pointers about to be kfree()'ed.

[ALSA] sound/pci: fix-up sleeping paths
ENS1370/1+ driver,ES1968 driver,Intel8x0 driver,VIA82xx driver
VIA82xx-modem driver,AC97 Codec,ALI5451 driver,CS46xx driver
MIXART driver,RME HDSP driver,Trident driver,YMFPCI driver
Description: Fix-up sleeping in sound/pci. These changes fall under the
following two categories:
1) Replace schedule_timeout() with msleep() to guarantee the
task delays as expected. This also involved replacing/removing
custom sleep functions.
2) Do not assume jiffies will only increment by one if you
request a 1 jiffy sleep, i.e. use time_after/time_before in
while loops.

Description: Fix-up sleeping in sound/pci. These changes fall under the

Description: Fix-up sleeping in sound/pci. These changes fall under the
following two categories:
1) Replace schedule_timeout() with msleep() to guarantee the
task delays as expected. This also involved replacing/removing
custom sleep functions.
2) Do not assume jiffies will only increment by one if you
request a 1 jiffy sleep, i.e. use time_after/time_before in
while loops.
