Added CONFIG_SND_AC97_POWER_SAVE kernel config to enable the support

powerdown register bits are dynamically controlled at each open/close

The mode is activated via power_save option for snd-ac97-codec
driver.  As default it's off.  It can be turned on/off on the fly
via sysfs, too.

Jon Masters 962f831f67 [PATCH] sound: fix hang in mpu401_uart.c
This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface
is non-existent or otherwise doesn't respond to commands but we issue IO
anyway.  snd_mpu401_uart_cmd now returns an error code that is passed up
the stack so that an open() will fail immediately in such cases.

Eventually discovered after wine/cxoffice would constantly cause hard
lockups on my desktop immediately after loading (emulating Windows too
well).  Turned out that I'd recently moved my sound cards around and using
/dev/sequencer now talks to a sound card with a broken MPU.

This second version changes -EFAULT to -EIO and frees open resources on
error too.  Test booted and seems to work ok.

Bjorn Helgaas f301ae6a69 [PATCH] pnp: mpu401: adjust pnp_register_driver signature
This series of patches removes the assumption that pnp_register_driver()
returns the number of devices claimed.  Returning the count is unreliable
because devices may be hot-plugged in the future.  (Many devices don't support
hot-plug, of course, but PNP in general does.)

This changes the convention to "zero for success, or a negative error value,"
which matches pci_register_driver(), acpi_bus_register_driver(), and
platform_driver_register().

If drivers need to know the number of devices, they can count calls to their
.probe() methods.

This patch:

Remove the assumption that pnp_register_driver() returns the number of devices
claimed.
