There should be a pci_dev_put when breaking out of a loop that iterates
over calls to pci_get_device and similar functions.
In this case, the return under the initial if needs a pci_dev_put in the
same way that the return under the subsequent for loop has a pci_dev_put.
This was fixed using the following semantic patch.
// <smpl>
@@
type T;
identifier d;
expression e;
@@
T *d;
...
while ((d = \(pci_get_device\|pci_get_device_reverse\|pci_get_subsys\|pci_get_class\)(..., d)) != NULL)
{... when != pci_dev_put(d)
when != e = d
(
return d;
|
+ pci_dev_put(d);
? return ...;
)
...}
// </smpl>

The recent change of include/asm-generic/dma-mapping-broken.h breaks
the build without CONFIG_HAS_DMA. This patch is an ad hoc fix.

This automatically fixes bugs in the old proc code.

This patch converts most uses of list_for_each to list_for_each_entry all
across alsa. In some place apparently an item can be on a list with
different pointers so of course that isn't compatible with list_for_each, I
therefore didn't touch those places.

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.

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.

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.

- 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.

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!
