Keep MAX98090 interrupt requested after i2c device probing as long as the
driver is loaded. This fixes the issue where subsequent codec probe
max98090_probe() call fails in interrupt request since interrupt wasn't
freed over codec remove-reprobe cycle.

This fixes a bug when using the SOC_DOUBLE_R_RANGE_TLV macro in
the invert mode. In the non-invert case, e.g.
SOC_DOUBLE_R_RANGE_TLV("<name>", <reg_l>, <reg_r>,
0, 40, 255, 0, <tlv>)
the range sent to the hardware is 40..255, but in the invert case:
SOC_DOUBLE_R_RANGE_TLV("<name>", <reg_l>, <reg_r>,
0, 40, 255, 1, <tlv>)
the range 215..0 was being sent to the hardware. This commit
corrects this to 255..40 so it is consistent with the non-invert
case.

Stephen Rothwell's compiler did something amazing: it unrolled a
loop, discovered that one iteration of that loop contained an
always-true test, and emitted a warning that will IMO only serve
to convince people to disable the warning.
That bogus warning caused me to wonder what prompted such an
absurdity from his compiler, and I discovered that the code in
question was, in fact, completely wrong -- I was looking things
up in the wrong array.
This affects 3.16 as well, but the only effect is to screw up
the error checking a bit. vdso2c's output is unaffected.

There is possibility with misconfigured pins that interrupt occurs instantly
after setting irq_set_chained_handler() in gpiochip_set_chained_irqchip().
Now if handler gets called before irq_set_handler_data() the handler gets
NULL handler data.
Fix this by moving irq_set_handler_data() call before
irq_set_chained_handler() in gpiochip_set_chained_irqchip().

If et131x_rx_dma_memory_alloc() allocates rx_ring->fbr[0] but fails to
allocate rx_ring->fbr[1], this leaves fbr[0]->ring_virtaddr with the
possibility of being accessed in et131x_rx_dma_memory_free() as it
contains a random value, potentially causing an oops.
Fix this by zeroing the fbr memory on allocation. Subsequent frees of
this fbr memory explicitly zeros the ring_virtaddr value.

HDMI currently stops working after a system suspend/resume cycle. The
cause is that the mode setting states in hardware gets lost and isn't
restored across the suspend/resume cycle.
The patch adds a very basic suspend/resume support to imx-drm driver,
and calls drm_helper_resume_force_mode() in .resume hook to restore the
mode setting states, so that HDMI can continue working after a system
suspend/resume cycle.
Since the suspend/resume hook can be called with drm_device pointer
being NULL from driver data, we need a check on the pointer in the
hooks. And to avoid using a stale pointer from driver data, it also
clears driver data in .unload hook.

All those ipu_*_put() calls in ipu_plane_dpms() are unnecessary,
because the only occurrence of ipu_plane_dpms() with 'mode' not being
DRM_MODE_DPMS_ON is in function ipu_disable_plane(), which already
has a ipu_plane_put_resources() call to put those ipu resources right
after ipu_plane_dpms().
So with those redundant ipu_*_put() calls removed from ipu_plane_dpms(),
the only left code in the function is ipu_plane_enable|disable(). Thus,
we can just call ipu_plane_enable|disable() as needed directly and
remove the ipu_plane_dpms() function completely.

In win8 we have a feature that allows for interrupt driven flow management
for host/guest communication. For instance, if the host were blocked because
there was no space available in the ringbuffer, the host could request that the
guest send an interrupt when space becomes available in the ringbuffer (when
the guest drains the ringbuffer).
While this feature was implemented in the guest a while ago, we had not
advertised that the guest supported this feature. This patch advertises
the support to the host.
For pre-win8 hosts, this has no effect since the size of the ringbuffer
control structure has not changed and all changes have been backward
compatible - unused/reserved space has been used to implement this
feature.
In this version of the patch I have cleaned up the commit log based on
feedback from Greg KH.

Minimize failures in this function by pre-allocating the buffer
for posting messages. The hypercall for posting the message can fail
for a number of reasons:
1. Transient resource related issues
2. Buffer alignment
3. Buffer cannot span a page boundry
We address issues 2 and 3 by preallocating a per-cpu page for the buffer.
Transient resource related failures are handled by retrying by the callers
of this function.
This patch is based on the investigation
done by Dexuan Cui <decui@microsoft.com>.
