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
not known how to do this in VBOX or if it is even possible. Since
this page-flip implementation does not try to sync the page-flip
to vertical blanking, tearing effects are possible.

Merge tag 'iio-for-4.19c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

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.

The enumerated type DM_CCK_Rx_Path_Method is used as a container for
constant definitions, rather then an enumerated type enabling compiler
type checking. To correct this, the variable which uses the constants,
defined by the enumeration, has had its type changed from a u8 to the
enumeration.

Additionally the type has been moved above the structure where the type
is used, to avoid compiler error. The typedef has been removed from the
enumerated type to clear the checkpatch issue with defining new types.
The name of the type has been changed to cck_rx_path_method to clear
the checkpatch issue with CamelCase naming. And the enumerated constant
CCK_Rx_Version_MAX has been removed, since it is never used in code.

The changes are all coding style in nature and so should have no
impact on runtime code execution.
