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.

This modifies vbox_crtc_do_set_base() to take a new framebuffer to
be activated, instead of the existing framebuffer attached to the crtc.
This change allows the function to be given the new framebuffer from
a page-flip request.

This is a somewhat sneaky late pull request given Linus has announced

things queued for the merge window.

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 enumerated type dm_dig_cs_ratio_e is never actually used as a type,
but only as a collection of related constants. This is because the
variables, which use the defined constant values, are defined as being
of type u8 rather then tne enumerated type. This omission negates the
possibility of taking advantage of compiler type checking.
To enable the use of compiler type checking of the enumeration the two
variables, (curcs_ratio_state & precs_ratio_state), which use the type's
constants have their types changed from u8 to enum dig_cck_cs_ratio_state.
Additionally the types declaration has been moved above the dig
structure, where the type is used. The 'typedef' keyword has been
removed from the type to clear the checkpatch issue with defining new
types. And the constant DIG_CS_MAX has been removed since this is never

The enumerated type dm_ratr_sta_e was defined in the file

file. The only variable which uses this enumerated type is 'ratr_state',

drivers/staging/rtl8192u/r8192U.h.
To clarify and place the enumerated type close to where it is used the
type was moved to the drivers/staging/rtl8192u/r8192U.h file.
In addition the member variable 'ratr_state' which uses the enumerated
constants was declared as being of type 'u8'. This negates any advantage
of the enumerated type, compiler type-checking, so that member variable's
type has been changed to being of the enumerated type.
The typedef from the enumerated type has been removed to clear the

Refactor the use of the enumerated type dm_dig_sta_e, which is not
actually used for type checking by the compiler.
The typedef of dm_dig_sta_e is removed to clear the checkpatch issue
with defining new types, and the enumerated type is left with the name
enum dynamic_init_gain_state
The enumerated type defines values for the enumeration, which are used
by both dig_state and dig_highpwr_state, (members of the struct dig).
Both of those variables were defined as being of type u8. This negates
any usefulness of the use of the enumeration, (compiler type checking).
To make use of the compiler's type-checking the two member variables,
dig_state and dig_highpwr_state have been changed to being of type
enum dynamic_init_gain_state. The enumerated type has been moved above
the struct dig definition so that the enumeration is already defined
when the compiler reaches the two types using the enumerated type.
These changes, whilst convoluted, are purely coding style in nature and
