8fc24426f1 Revert "ALSA: hda - Allow power_save_controller option override DCAPS"
This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

f1a9a149ab HID: magicmouse: fix race between input_register() and probe()
Since kernel 3.7, it appears that the input registration occured before
the end of magicmouse_setup_input(). This is shown by receiving a lot of
"EV_SYN SYN_REPORT 1" instead of normal "EV_SYN SYN_REPORT 0".
This value means that the output buffer is full, and the user space
is loosing events.

Using .input_configured guarantees that the race is not occuring, and that
the call of "input_set_events_per_packet(input, 60)" is taken into account
by input_register().

69a2bac898 rt2x00: rt2x00pci: fix build error on Ralink RT3x5x SoCs
The rt2800pci driver supports the built-in wireless
MAC of the Ralink RT3x5x SoCs. However building the
driver for these SoCs leads to the following error:

    LD      init/built-in.o
  drivers/built-in.o: In function `rt2800pci_rxdone_tasklet':
  <...>/drivers/net/wireless/rt2x00/rt2800pci.c:1012: undefined reference to `rt2x00pci_rxdone'
  drivers/built-in.o:(.rodata+0x4780): undefined reference to `rt2x00pci_initialize'
  drivers/built-in.o:(.rodata+0x4784): undefined reference to `rt2x00pci_uninitialize'
  drivers/built-in.o:(.rodata+0x47bc): undefined reference to `rt2x00pci_flush_queue'
  drivers/built-in.o:(.rodata+0x4818): undefined reference to `rt2x00pci_regbusy_read'
  make[5]: *** [vmlinux] Error 1

The missing functions are provided by the rt2x00pci
module. This module is only selected by the rt2800pci
driver if PCI support is enabled in the kernel, because
some parts of the rt2x00pci code depends on PCI support.

PCI support is not available on the RT3x5x SoCs because
those have no PCI host controller at all.

Move the non PCI specific code from rt2x00pci into a
separate module. This makes it possible to use that
code even if PCI support is disabled. The affected
functions are used by all of the rt2x00 PCI drivers
so select the new module for those drivers.

83589b30f1 rt2x00: rt2x00pci_regbusy_read() - only print register access failure once
BugLink: http://bugs.launchpad.net/bugs/1128840

It appears that when this register read fails it never recovers, so
I think there is no need to repeat the same error message ad infinitum.

f50b1cd374 ath9k: Re-enable interrupts after a channel change failure
ath_complete_reset will not be called if ath9k_hw_reset
is unsuccessful, so we need to re-enable intertupts to
balence the previous ath_prepare_reset call.  Also schedule a
reset as a best effort method to recover the chip from
whatever state caused the channel change failure.
