[PATCH] mark struct file_operations const 9

2007-02-12T17:48:46Z

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Now that everyone uses snd_ctl_new1() and noone is using snd_ctl_new() anymore, we can make it static. Signed-off-by: Adrian Bunk Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] alsa core: convert to list_for_each_entry*

2007-02-09T08:00:10Z

This patch converts most uses of list_for_each to list_for_each_entry all across alsa. In some place apparently an item can be on a list with different pointers so of course that isn't compatible with list_for_each, I therefore didn't touch those places.

[ALSA] Fix substream selection in PCM and rawmidi

2006-09-23T08:39:59Z

The PCM and rawmidi substreams can be selected explicitly by opening control handle and set via *_PREFER_SUBDEVICE ioctl. But, when multiple controls are opened, the driver gets confused. The patch fixes the initialization of prefer_*_subdevice and the check of multiple controls. The first set subdevice is picked up as the valid one.

[ALSA] Unregister device files at disconnection

2006-09-23T08:36:58Z

Orignally proposed by Sam Revitch . Unregister device files at disconnection to avoid the futher accesses. Also, the dev_unregister callback is removed and replaced with the combination of disconnect + free. A new function snd_card_free_when_closed() is introduced, which is used in USB disconnect callback. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela
