d001544ded [ALSA] dynamic minors (6/6): increase maximum number of sound cards
Modules: ALSA Core,Memalloc module,ALSA sequencer

With dynamic minor numbers, we can increase the number of sound cards.

This requires that the sequencer client numbers of some kernel drivers
are allocated dynamically, too.

204bdb1b50 [ALSA] dynamic minors (5/6): reduce maximum number of MIDI devices per card
Modules: ALSA sequencer,Generic drivers

To allow increasing the maximum number of sound cards, we have to limit
the number of sequencer clients per card because client numbers are
still allocated statically.

Reducing the number of clients to four limits the number of sequencer
MIDI ports to 1024 per card.

f87135f56c [ALSA] dynamic minors (3/6): store device-specific object pointers dynamically
Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.

This makes the device type modules independent of the minor number
encoding.

2af677fc88 [ALSA] dynamic minors (1/6): store device type in struct snd_minor
Instead of a comment string, store the device type in the snd_minor
structure.  This makes snd_minor more flexible, and has the nice side
effect that we don't need anymore to create a separate snd_minor
template for registering a device but can pass the file_operations
directly to snd_register_device().

87ef7779be [ALSA] seq-timer: restrict timer frequencies
Modules: ALSA sequencer

When no default timer frequency has been set, initialize_timer() just
uses the maximum frequency supported by the timer, which is ridiculously
high on 96 kHz timers.

This patch introduces a default frequency of 1000 Hz for this case, and
makes sure that a frequency set by the user isn't too high.

Remove snd_runtime_check() macro.
This macro worsens the readability of codes.  They should be either

Also, the assert displays stack-dump, instead of only the last caller

dd0fc66fb3 [PATCH] gfp flags annotations - part 1
- added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

77933d7276 [PATCH] clean up inline static vs static inline
`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

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.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
