2006-09-23[ALSA] system timer: remove unused snd_timer_system_private.timer fieldClemens Ladisch
Remove the snd_timer_system_private structure's timer field that was never used. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] timer: fix timer reschedulingClemens Ladisch
When checking whether a hardware timer needs to be rescheduled, we have to compare against the previously scheduled interval and not against the actual interval between the last two interrupts. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] system timer: clear correction value when timer stopsClemens Ladisch
Do not retain the old correction value when the timer was stopped. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] system timer: accumulate correction for multiple lost ticksClemens Ladisch
When multiple timer interrupts arrive too late, correct for all delays instead of ignoring the earlier ones. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] system timer: fix lost ticks correction adjustmentClemens Ladisch
Fix the adjustment of the lost ticks correction variable in the case when the correction has been fully taken into account in the next timer expiration value. Subtracting the scheduled ticks value would result in an underflow. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] Control API - more robust TLV implementationJaroslav Kysela

2006-09-23[ALSA] Deprecate snd_card_free_in_thread()Takashi Iwai
Deprecated snd_card_free_in_thread(), replaced with snd_card_free_when_closed(). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] Unregister device files at disconnectionTakashi Iwai
Orignally proposed by Sam Revitch <sam.revitch@gmail.com>. 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 <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

Drop the snd_minor structure's name field that was just a helper for devfs device deregistration. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-07-03[PATCH] lockdep: annotate sound/core/seq/seq_device.cArjan van de Ven
The ops structure has complex locking rules, where not all ops are equal, some are subordinate on others for some complex sound cards. This requires for lockdep checking that each individual reg_mutex is considered in separation for its locking rules. Has no effect on non-lockdep kernels.

2006-06-28[ALSA] Fix misuse of __list_add() in seq_ports.cTakashi Iwai
seq_ports.c::snd_seq_delete_all_ports() uses __list_add() to replace the whole list entries. This results in BUG() with recent FC5 kernel due to a sanity check in __list_add(). The patch fixes this misue of __list_add() by using standard macros instead (although a bit more code is needed).
