ALSA: hdspm: 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() manually on the error
from the probe callback.

ALSA: hdspm: Allocate resources with device-managed APIs

This patch converts the resource management in PCI hdspm 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: hdspm: Replace tasklet with work

The tasklet is an old API that should be deprecated, usually can be
converted to another decent API. In HDSP-MADI driver, a tasklet is
still used for offloading the MIDI I/O handling (optional via mixer
switch). It can be achieved gracefully with a work queued, too.

This patch replaces the tasklet usage in HDSP-MADI driver with a
simple work. The conversion is fairly straightforward. The only
significant difference is that the work initialization is moved to the
right place in snd_hdspm_create() and cancel_work_sync() is always
called in snd_hdspm_free() to assure killing the pending works.

By taking into account the mapping from logical to DMA channels when

HDSPe AIO card are now correctly captured and played back in single speed

Since the mapping is an identity mapping for all cards except AIO and

an AIO card. The patch needs testing on other cards, in particular RayDAT.

Note: this patch does not solve ADAT capture and playback issues in double

ALSA: hdspm - potential info leak in snd_hdspm_hwdep_ioctl()

Smatch has a new check for Rosenberg type information leaks where

Newer RME cards like RayDAT and AIO support 32 samples per period. This

Since {1,1,1} is also the representation for 8192 samples/period on

On newer RME cards like RayDAT and AIO, the 8192 samples per period size

To make this more obvious to future developers, let's reorder the array

4096 ({1,1,0}) and finally 32 ({1,1,1}).

ALSA: hdspm - Fix reported external sample rate on RME MADI and MADIface

In slave mode, the card can only detect the base frequency (32..48kHz)

rate is this base frequency multiplied by 1, 2 or 4 depending on the
speed mode.

This patch enables 64..192kHz sample rates in clock slave mode, which
failed before due to an alleged sample rate mismatch between the MADI

are not altered or zeroed before being copied back to the user. This
patch takes care of it.

[ALSA] sound/pci/rme9652/hdspm.c: stop inlining largish static functions

sound/pci/rme9652/hdspm.c has unusually large number of static inline

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.
