056622053b ALSA: seq: Define driver object in each driver
This patch moves the driver object initialization and allocation to
each driver's module init/exit code like other normal drivers.  The
snd_seq_driver struct is now published in seq_device.h, and each
driver is responsible to define it with proper driver attributes
(name, probe and remove) with snd_seq_driver specific attributes as id
and argsize fields.  The helper functions snd_seq_driver_register(),
snd_seq_driver_unregister() and module_snd_seq_driver() are used for
simplifying codes.

1730fd9cce ALSA: fix emu8000 DRAM sizing for AWE64 Value
Applicable to any kernel since 2013:

The special case added in commit 1338fc97d0 did not handle the possibility
that the address space on an AWE64 Value would wrap around at 512 KiB.  That
is what it does, so the memory is still not detected on those cards.

Fix that with a logic clean-up that eliminates the need for a special case.

fa60c06569 ALSA: wss: Remove (almost) always NULL parameters
Most callers of snd_wss_pcm(), snd_wss_timer() and snd_cs4236_pcm() pass
NULL as the last parameter, some callers pass a pointer but never use it
after the function has been called and only a few callers pass a pointer and
actually use it. The later is only the case for snd_wss_pcm() for
snd_cs4236_pcm() and it is possible to get the same PCM object by accessing
the pcm field of the snd_wss struct that was passed as the first parameter.

This function removes the last parameters from the functions mentioned above
and updates the callers which used it to use chip->pcm instead. This allows
us to slightly simplify the functions since they don't have to check and set
the last parameter anymore which makes the code slightly shorter and
cleaner.

But, looking at the reality, the probability we'll have a new code for

ce816fa88c Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP
If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally.  So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available.  I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

	$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

fb615499f0 ALSA: opti9xx: Fix conflicting driver object name
The recent commit to delay the release of kobject triggered NULL
dereferences of opti9xx drivers.  The cause is that all
snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers
register the PnP card driver with the very same name, and also
snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with
the same name, too.  When these drivers are built in, quick
"register-release-and-re-register" actions occur, and this results in
Oops because of the same name is assigned to the kobject.

The fix is simply to assign individual names.  As a bonus, by using
KBUILD_MODNAME, the patch reduces more lines than it adds.

The fix is based on the suggestion by Russell King.

edb6689386 ALSA: sound/isa/opti9xx/miro.c: eliminate possible double free
snd_miro_probe is a static function that is only called twice in the file
that defines it.  At each call site, its argument is freed using
snd_card_free.  Thus, there is no need for snd_miro_probe to call
snd_card_free on its argument on any of its error exit paths.

Because snd_card_free both reads the fields of its argument and kfrees its
argments, the results of the second snd_card_free should be unpredictable.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
