The report descriptor is read by user space (via the Service
Discovery Protocol), so it is only available during the ioctl
to connect. However, the HID probe function that needs the
descriptor might not be called until a specific module is
loaded. Keep a copy of the descriptor so it is available for
later use.

The functionality bit vector is always returned as a little-endian
32-bit number by the device, so it must be byte-swapped to the host
endianness.
On the other hand, the delay value is handled by the USB stack, so no
byte swapping is needed on our side.
This fixes bug #15105:

The new cs5535-* drivers use PCI header config info rather than MSRs to
determine the memory region to use for things like GPIOs and MFGPTs. As
anticipated, we've run into a buggy BIOS:
[ 0.081818] pci 0000:00:14.0: reg 10: [io 0x6000-0x7fff]
[ 0.081906] pci 0000:00:14.0: reg 14: [io 0x6100-0x61ff]
[ 0.082015] pci 0000:00:14.0: reg 18: [io 0x6200-0x63ff]
[ 0.082917] pci 0000:00:14.2: reg 20: [io 0xe000-0xe00f]
[ 0.083551] pci 0000:00:15.0: reg 10: [mem 0xa0010000-0xa0010fff]
[ 0.084436] pci 0000:00:15.1: reg 10: [mem 0xa0011000-0xa0011fff]
[ 0.088816] PCI: pci_cache_line_size set to 32 bytes
[ 0.088938] pci 0000:00:14.0: address space collision: [io 0x6100-0x61ff] already in use
[ 0.089052] pci 0000:00:14.0: can't reserve [io 0x6100-0x61ff]
This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge
device's BAR0 to 8k. In reality, it should be 8 bytes (BAR0 is used for
SMBus stuff). This quirk checks for an incorrect size, and resets it
accordingly.

Add code to start the CMT timer on clocksource resume. While at it handle
the suspend case as well. Remove the platform device specific suspend
calls.
This makes sure the timer is started during sysdev_resume(). Without this
patch the clocksource may be read as suspended, this after sysdev resume
but before platform device resume.

Add a clocksource suspend callback. This callback can be used by the
clocksource driver to shutdown and perform any kind of late suspend
activities even though the clocksource driver itself is a non-sysdev
driver.
One example where this is useful is to fix the sh_cmt.c platform driver
that today suspends using the platform bus and shuts down the clocksource
too early.
With this callback in place the sh_cmt driver will suspend using the
clocksource and clockevent hooks and leave the platform device pm
callbacks unused.

It is possible (and expected) for there to be holes in the h->drv[]
array, that is, some elements may be NULL pointers. cciss_seq_show
needs to be made aware of this possibility to avoid an Oops.
To reproduce the Oops which this fixes:
1) Create two "arrays" in the Array Configuratino Utility and
several logical drives on each array.
2) cat /proc/driver/cciss/cciss* in an infinite loop
3) delete some of the logical drives in the first "array."

My sound codec seems sometimes (very rarely) to omit interrupts (ALC268)
However, interrupt mode still works.
Thus if we get timeout, poll the codec once.
If we get 3 such polls in a row, then switch to polling mode.

I found that the sampling rate locking setting of the ice1712 sound driver
was only half-respected : when the driver was locked to, let's say, 44100Hz,
and a usermode app was requesting 48000Hz playback, the request was succesful
although the soundcard would continue to run at 44100Hz.
Here's a patch that will make those requests to fail.

The current root hub polling code exhibits a spinlock recursion on the
private controller lock. r8a66597_root_hub_control() is called from
r8a66597_timer() which grabs the lock and disables IRQs. The following
chain emerges:
r8a66597_timer() <-- lock taken
r8a66597_root_hub_control()
r8a66597_check_syssts()
usb_hcd_poll_rh_status() <-- acquires the same lock
/* insert death here */
The entire chain requires IRQs to be disabled, so we just unlock and
relock around the call to usb_hcd_poll_rh_status() while leaving the
IRQ state unchanged.

This implements the same D-cache flushing logic for r8a66597-hcd as
Catalin's isp1760 (http://patchwork.kernel.org/patch/76391/) change,
with the same note applying here as well:
When the HDC driver writes the data to the transfer buffers it
pollutes the D-cache (unlike DMA drivers where the device writes
the data). If the corresponding pages get mapped into user space,
there are no additional cache flushing operations performed and
this causes random user space faults on architectures with
separate I and D caches (Harvard) or those with aliasing D-cache.
This fixes up crashes during USB boot on SH7724 and others:

In suspend path we unmap the GART table while in cleaning up
path we will unbind buffer and thus try to write to unmapped
GART leading to oops. In order to avoid this we don't call the
suspend path in cleanup path. Cleanup path is clever enough
to desactive GPU like the suspend path is doing, thus this was
redondant.
