ALSA: ca0106: Fix the missing snd_card_free() call at probe error

The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature. Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.

ALSA: ca0106: Rename register macro names

ca0106 driver code uses too generic names for its register definitions

code. This patch renames (some of) those register definitions with
CA0106_ prefix to avoid the conflicts.

ALSA: ca0106: Allocate resources with device-managed APIs

This patch converts the resource management in PCI ca0106 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.

This should give no user-visible functional changes.

[ALSA] ca0106: power down SPI DAC channels when not in use

For cards with an SPI DAC (SB Live 24-bit / Audigy SE), power down channels
0-2 when not in use. They are powered up on PCM open and down again on PCM
close. Channel 4 (== Front) is not powered down, as it is used for capture
feedback. Powering it down would effectively kill line in pass-through.

[ALSA] ca0106: Add analog mute controls for cards with SPI DAC

Add four mute controls for the analog output channels for cards that use
an SPI DAC, like the SB0570 SB Live! 24-bit / Audigy SE. The Wolfson DAC
doesn't support muting left/right so the controls are mono.
The chip state struct gets a 32-byte array to act as a shadow of the spi
dac registers. Only two registers are used for mute, but more would be
needed for analog gain, de-emphasis, DAC power down, phase inversion, and
other features.

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.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.

(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.

(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

[ALSA] snd-ca0106, snd-emu10k1: Add symlink in the sys tree.

CA0106 driver,EMU10K1/EMU10K2 driver
A thread appeared on the LKML. This patch implements the fix.

Question:
in sysfs, /sys/bus/*/drivers lists the driver names, with their exported .name (eg. '.name = 'EMU10K1_Audigy'' in the module code, from now on 'driver name'). In /sys/modules, the kernel modules are listed with their module name, eg. snd_emu10k1. However, it seems to me that in sysfs, there is no way in particular to tell, which module has which .name. That is, that snd_emu10k1 is EMU10K1_Audigy and vice versa.

I wonder whether it wouldn't be possible to add a symlink to the particular module from the driver, and/or from the module to the driver, so the list of devices handled by the module and the module name would be accessible. This way, I would know which driver name corresponds to which module name and vice versa.

Answer:
For PCI drivers, just add the line:
.owner = THIS_MODULE,

to their struct pci_driver definition and you will get the symlink
created for you.
