Use is_multicast_ether_addr instead of custom IS_MCAST.
The variable for the result of IS_MCAST was only used in the
if conditional. So remove the extra variable and move the call
to is_multicast_ether_addr into the conditional.

This patch fixes the sparse warnings by making use of le32_to_cpus() &
cpu_to_le32s() conversion API's.
Remove the unnecessary byte-order conversion in
wilc_wlan_parse_response_frame() as the data is copied using individual
byte operation.
Also added the byte-order conversion for 'header' in
wilc_wfi_monitor_rx() & wilc_wfi_p2p_rx() as received in LE byte-order.

Adds crtc page-flip support by passing the new requested framebuffer
to vbox_crtc_do_set_base().
Note there is no attempt to support vblank interrupts, it's not

this page-flip implementation does not try to sync the page-flip

Third set of IIO new device support, cleanups and features for the 4.19 cycle.
This is a somewhat sneaky late pull request given Linus has announced
a likely 1 week delay. If it is too late I'll resend after the merge
window. I merged in the fixes branch as those are primarily around
things queued for the merge window.
Particulary good to see the output of our Himanshu Jha, a GSOC student
who developed the bme680 driver.
New device support:
* bme680 gas sensor (with temperature, humidity and pressure)
- new driver to support this device
* vcn4000
- support vcnl4200 (lots of rework to allow this)
- ids added for VCNL4010 and VCNL4020 sensors
New features:
* ad9523
- support the various external signal options via gpios.
Cleanups and fixes
* ad_sigma_delta
- unsigned long for a timeout.
* ad9523
- fix a wrong return value that was indicating successful write failed
and might lead to an infinite loop.
* si1133
- fix an impossible test.
- fix an uninitialsed variable by reading from the device in all paths.
* xilinx xadc
- check for return values in clk related functions
- limit the pcap clock frequency to supported ranges.
- stash the irq to avoid calling platform_get_irq from the remove path.
- ensure the irq is actually requested before we enable the hardware to
output it.

Simplify the logic of ASIC health discovery.
ASIC device can indicate its health state as a good, booting or dormant.
During ASIC reset the device is dropped to dormant state and should get to
the stable good health state through the intermediate booting state.
The sequence for getting to the steady state health after reset is:
(dormant -> booting -> good)+.
Initial implementation assumes that ?good? within this sequence is always
repeated twice and device is getting steady state only after the second
?good?. This patch removes this dependency, since the second ?good? is
received because of the noise on line and can be ignored. Device reaches
steady state after the first ?good? is received.

The change of ipoib_ah data structure with adding "valid" flag and
checks of ah->valid in ipoib_start_xmit affected multicast packet flow.
Since the multicast flow doesn't invoke path_rec_start, "ah->valid" flag
remains unset, so that ipoib_start_xmit end up with neigh_refresh_path
instead of sending the packet using neigh.
"ah->valid" has to be set in multicast send flow. As a result IPoIB
starts sending packets via neigh immediately and eliminates 60sec delay
of neigh keep alive interval.
The typical example of this issue are two sequential arpings:
arping 11.134.208.9 -> got response (mcast_send)
arping 11.134.208.9 -> no response (ah->valid = 0)

The disassociate function was broken by design because it failed all
commands. This prevents userspace from calling destroy on a uobject after
it has detected a device fatal error and thus reclaiming the resources in
userspace is prevented.
This fix is now straightforward, when anything destroys a uobject that is
not the user the object remains on the IDR with a NULL context and object
pointer. All lookup locking modes other than DESTROY will fail. When the
user ultimately calls the destroy function it is simply dropped from the
IDR while any related information is returned.

This does the same as the patch before, except for ioctl. The rules are
the same, but for the ioctl methods the core code handles setting up the
uobject.
- Retrieve the ib_dev from the uobject->context->device. This is
safe under ioctl as the core has already done rdma_alloc_begin_uobject
and so CREATE calls are entirely protected by the rwsem.
- Retrieve the ib_dev from uobject->object
- Call ib_uverbs_get_ucontext()

This is a step to get rid of the global check for disassociation. In this
model, the ib_dev is not proven to be valid by the core code and cannot be
provided to the method. Instead, every method decides if it is able to
run after disassociation and obtains the ib_dev using one of three
different approaches:
- Call srcu_dereference on the udevice's ib_dev. As before, this means
the method cannot be called after disassociation begins.
(eg alloc ucontext)
- Retrieve the ib_dev from the ucontext, via ib_uverbs_get_ucontext()
- Retrieve the ib_dev from the uobject->object after checking
under SRCU if disassociation has started (eg uobj_get)
Largely, the code is all ready for this, the main work is to provide a
ib_dev after calling uobj_alloc(). The few other places simply use
ib_uverbs_get_ucontext() to get the ib_dev.
This flexibility will let the next patches allow destroy to operate
after disassociation.

Commands that are reading/writing to objects can test for an ongoing

After all the recent structural changes this is now straightforward, hold
the hw_destroy_rwsem across the entire uobject creation. We already take
this semaphore on the success path, so holding it a bit longer is not
going to change the performance.
After this change none of the create callbacks require the
disassociate_srcu lock to be correct.

After all the recent structural changes this is now straightfoward, hoist
the hw_destroy_rwsem up out of rdma_destroy_explicit and wrap it around
the uobject write lock as well as the destroy.
This is necessary as obtaining a write lock concurrently with
uverbs_destroy_ufile_hw() will cause malfunction.
After this change none of the destroy callbacks require the
disassociate_srcu lock to be correct.
This requires introducing a new lookup mode, UVERBS_LOOKUP_DESTROY as the
IOCTL interface needs to hold an unlocked kref until all command
verification is completed.

There are several flows that can destroy a uobject and each one is
minimized and sprinkled throughout the code base, making it difficult to
understand and very hard to modify the destroy path.
Consolidate all of these into uverbs_destroy_uobject() and call it in all
cases where a uobject has to be destroyed.
This makes one change to the lifecycle, during any abort (eg when
alloc_commit is not called) we always call out to alloc_abort, even if
remove_commit needs to be called to delete a HW object.
This also renames RDMA_REMOVE_DURING_CLEANUP to RDMA_REMOVE_ABORT to
clarify its actual usage and revises some of the comments to reflect what
the life cycle is for the type implementation.

The ridiculous dance with uobj_remove_commit() is not needed, the write
path can follow the same flow as ioctl - lock and destroy the HW object
then use the data left over in the uobject to form the response to
userspace.

caller.

The core code will destroy the HW object on behalf of the method, if the
method provides an implementation it must simply copy data from the stub
