2006-07-12[ALSA] remove unused snd_minor.name fieldClemens Ladisch
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).
