This patch contains the following possible cleanups:
- pci/hda/hda_proc.c should #include 'hda_local.h' for including the
  prototype of it's global function snd_hda_codec_proc_new()
- core/rawmidi.c: make the needlessly global and EXPORT_SYMBOL'ed
  function snd_rawmidi_info() static

When the output buffer size is changed, runtime->avail must be
adjusted to the new size; otherwise, draining of a bigger buffer would
appear to fail because avail does not reach buffer_size.

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.

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.

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.

Store the snd_minor structure pointers in one array instead of using a
separate list for each card.  This simplifies the mapping from device
files to minor struct by removing the need to know about the encoding
of the card number in the minor number.
Signed-off-by: NClemens Ladisch <clemens@ladisch.de>

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().

Earlier I unifdefed PageCompound, so that snd_pcm_mmap_control_nopage and
others can give out a 0-order component of a higher-order page, which won't
be mistakenly freed when zap_pte_range unmaps it.  But many Bad page states
reported a PG_reserved was freed after all: I had missed that we need to
say __GFP_COMP to get compound page behaviour.

Some of these higher-order pages are allocated by snd_malloc_pages, some by
snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has
no gfp arg, so add __GFP_COMP into its sparc32/64 implementations.

I'm still rather puzzled that DRM seems not to need a similar change.

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.
