ALSA: use correct lock in snd_ctl_dev_disconnect()

2008-11-10T18:50:06Z

commit d8009882e9f5e1a76986c741f071edd2ad760c97 upstream The lock used in snd_ctl_dev_disconnect() should be card->ctl_files_rwlock for protection of card->ctl_files entries, instead of card->controls_rwsem.

[ALSA] Remove sound/driver.h

2008-01-31T16:29:48Z

This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Remove indirect control access

2008-01-31T16:29:46Z

This patch removes the indirect control access to the control elements. The indirect access has never been used and is even broken on 32bit ioctl wrapper. Let's clean it up. The pointers still remain in snd_ctl_elem_* structs just to make sure that the struct size won't change. Once after checking the size consistency, we can get rid of them, too.

[ALSA] sound/core/control.c: hard-irq-safe -> hard-irq-unsafe lock warning

2007-10-23T06:07:55Z

The lock grabbed in snd_ctl_empty_read_queue() is hardirq-unsafe but we hold an hardirq-safe one already, so make the &ctl->read_lock also hard-irq-safe. Signed-off-by: Borislav Petkov Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Add helper functions for frequently used callbacks

2007-10-16T13:57:44Z

Added helper functions for frequenty used callbacks: snd_ctl_boolean_mono_info() and snd_ctl_boolean_stereo_info() Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07Z

Remove includes of where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs). Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[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

[ALSA] make sound/core/control.c:snd_ctl_new() static

2007-02-09T08:01:40Z

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
