Takashi Iwai be93709cb1 ALSA: doc: Recommend the use of snd_ctl_elem_info()
Instead of the open code for the info call back of enum elements,
recommend the use of snd_ctl_elem_info(), which will reduce lots of
codes.

Takashi Iwai 393aa9c1cc ALSA: Mandate to pass a device pointer at card creation time
This is a part of preliminary works for modernizing the ALSA device
structure.  So far, we set card->dev at later point after the object
creation.  Because of this, the core layer doesn't always know which
device is being handled before it's actually registered, and it makes
impossible to show the device in error messages, for example.  The
first goal is to achieve a proper struct device initialization at the
very beginning of probing.

As a first step, this patch introduces snd_card_new() function (yes
there was the same named function in the very past), in order to
receive the parent device pointer from the very beginning.
snd_card_create() is marked as deprecated.

At this point, there is no functional change other than that.  The
actual change of the device creation scheme will follow later.

Christine Spang d5702162f8 ALSA: Make snd_BUG_ON() always evaluate and return the conditional expression
Having snd_BUG_ON() only evaluate its conditional when CONFIG_SND_DEBUG
is set leads to frequent bugs, since other similar macros in the kernel
have different behavior. Let's make snd_BUG_ON() act like those macros
so it will stop being accidentally misused.

Takashi Iwai a690a2a1eb ALSA: Fix wrong description about hw constraints
The definitions of hw constraint functions are wrongly placed, and the
description about the function is also wrong.
hw_rule_channels_by_format actually refines the channels depending on
the format, not vice versa.

Rusty Russell a67ff6a540 ALSA: module_param: make bool parameters really bool
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Clemens Ladisch dba8b46992 ALSA: mpu401: clean up interrupt specification
The semantics of snd_mpu401_uart_new()'s interrupt parameters are
somewhat counterintuitive:  To prevent the function from allocating its
own interrupt, either the irq number must be invalid, or the irq_flags
parameter must be zero.  At the same time, the irq parameter being
invalid specifies that the mpu401 code has to work without an interrupt
allocated by the caller.  This implies that, if there is an interrupt
and it is allocated by the caller, the irq parameter must be set to
a valid-looking number which then isn't actually used.

With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
which forces us to handle the parameters differently.

This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
device interrupt is handled by the caller, and makes the allocation of
the interrupt to depend only on the irq parameter.  As suggested by
Takashi, the irq_flags parameter was dropped because, when used, it had
the constant value IRQF_DISABLED.
