The regmap API usually assumes that bulk read operations will read a
range of registers but some I2C/SPI devices have certain registers for
which a such a read operation will return data from an internal FIFO
instead. Add an explicit API to support bulk read without range semantics.
Some linux drivers use regmap_bulk_read or regmap_raw_read for such
registers, for example mpu6050 or bmi150 from IIO. This only happens to
work because when caching is disabled a single regmap read op will map
to a single bus read op (as desired). This breaks if caching is enabled and
reg+1 happens to be a cacheable register.
Without regmap support refactoring a driver to enable regmap caching
requires separate I2C and SPI paths. This is exactly what regmap is
supposed to help avoid.

The reason of compiling error is:
Since -next collects and merges developing patches including common vfs

('vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=109b45090d7d3ce2797bb1ef7f70eead5bfe0ff3

Above vfs related patches has not been merged in staging tree, if we
submit those erofs patches to staging mailing list and after including
them in staging-{test,nexts} tree, it can easily cause compiling error.
We worked out some patches to adjust those vfs change, but now we just
submit them to -next tree temporarily to avoid compiling error.
For potentail conflict in between erofs and vfs changes in incoming
merge window, Stephen suggested that we can disable CONFIG_EROFS_FS
temporarily to pass merge window, and after that we can do restore by
reenabling CONFIG_EROFS_FS and applying those fixing patches. Also

byte array only dictates size if it's the largest element of the union.
The byte array and union add nothing.
The union has therefore been removed and the structure and access to
the structure simplified.
Additionally since one of the bitfield variables (ucAccessPolicy)
spans a byte boundary the base type of the bitfield has been changed
from u8 to u16. Compilers have probably moved on from having an issue
with this, call it OCD.
The changes are coding style in nature and should not impact runtime
code execution.

staging:rtl8192u: Remove union from aci_aifsn - Style
The union aci_aifsn is not used as a union, but only as a struct.
The union seems to have been used to ensure that the size of the
structure was only a single byte. That size is set by the bitfield
structure, adding a union with an unused byte adds nothing.
The union has been removed. This is a coding style change and
should not impact runtime code execution.

The only useful piece of information in the header comment of this
static function was the name of the function and parameters. That
is not useful information, given that they are in the C Source of
the function declaration, a few lines below the comment. The block
comment has been removed.
This is a coding style change, there should be no impact on runtime
code execution.

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.

staging: wilc1000: fix endianness warnings reported by sparse
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.

staging: vboxvideo: Add page-flip support
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.

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.
