Takashi Iwai 6974f8ad44 ALSA: pci: Avoid non-standard macro usage 
Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro.  The macro didn't give any better readability.

Kees Cook 6da2ec5605 treewide: kmalloc() -> kmalloc_array() 
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

with:

        kmalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kmalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

The Coccinelle script used for this was:

Ingo Molnar ac6424b981 sched/wait: Rename wait_queue_t => wait_queue_entry_t 
Rename:

	wait_queue_t		=>	wait_queue_entry_t

'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.

Start sorting this out by renaming it to 'wait_queue_entry_t'.

This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.

Takashi Iwai 934c2b6d0c ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/* 
The name argument of request_irq() appears in /proc/interrupts, and
it's quite ugly when the name entry contains a space or special letters.
In general, it's simpler and more readable when the module name appears
there, so let's replace all entries with KBUILD_MODNAME.

Takashi Iwai 9004acc70e [ALSA] Remove sound/driver.h 
This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

Fix schedule_timeout() use in alsa-kernel. Mostly just
	schedule_timeout(1) --> schedule_timeout_uninterruptible(1)
The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main,
delete a superfluous set_current_state() and in soc/soc-dapm.c replace an
_interruptible with _uninterruptible in some debug code; it's not waiting
for signals.

Clemens Ladisch 177a7cdbd1 [ALSA] ymfpci: fix volume handling of the 44.1 kHz slot 
The existing code for handling the 44.1 slot's volume has two problems:
the volume is not affected by the 'Wave Playback Volume' mixer control,
and the BUF441OUTVOL register, which is used to control the per-
substream volume for this slot, uses a different scale than the gain
fields of the other slots.
This patch makes the BUF441OUTVOL register a shadow of the
NATIVEDACOUTVOL register so that the Wave volume is consistent for all
substreams.
As a consequence of this, the per-substream PCM volume control gets no
longer activated for the substream using this slot.  The code for
(de)activating the mixer control is moved from the open/close to the
prepare/trigger_stop callbacks so that it is able to determine the
substream's slot.

Auke Kok 44c10138fd PCI: Change all drivers to use pci_device->revision 
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.
