staging: most: hdm-dim2: round up DBR memory for async/ctrl
As the DBR memory is allocated in units of DBR_BLOCK_SIZE, it is more
efficient to configure the DIM2 IP to use whole blocks of the DBR memory.
This patch ceils the DBR memory size used by the DIM2 IP for async/ctrl
channels.
staging: most: hdm-dim2: double size of DBR buffer
This patch increases the size of the asynchronous and control DBR buffers
in the Tx path to twice the max. message size. This patch is needed to
increase the throughput for big messages.
The DIM2 HDM checks the parameters passed to the function
configure_channel() and adapts the buffer sizes of the configuration
according to the hardware limitation. This patch is needed to init
the HAL layer with the correct values.

Second set of iio new device support, features and cleanups for the 4.9 cycle.
New device support
* ad8801 dac
- new driver supporting ad8801 and ad8803 DACs.
* adc12138
- new driver supporting TI adc12130/adc12132 and adc12138 ADCs.
* ltc2485 adc
- new driver
* mxc6255
- add support for the mxc6225 part name and fixup the ID check so it works.
* vz89x VOC sensor
- add support for the vz89te part which drops the voc_short channel and adds
CRCs compared to other supported parts.
New features
* core
- immutable triggers. These effectively grant exclusive control over a
trigger. The typical usecase is a device representing an analog part
(perhaps a MUX) that needs to control the sampling of a downstream
ADC.
- resource managed trigger registration and triggered_buffer_init.
- iio_push_event now protected against case of the event interface
registration not having yet occured. Only matters if an interrupt
can occur during this window - might happen on shared interrupt lines.
- helper to let a driver query if the trigger it is using is provided by
itself (using the convention of both device and trigger having the same
parent).
* tools
- iio-utils. Used channel modifier scaling in preference to generic scaling
when both exist.
* at91-adc
- Add support for touchscreen switches closure time needed by some newer
parts.
* stx104
- support the ADC channels on this ADC/DAC board. As these are the primary
feature of the board also move the driver to the iio/adc directory.
* sx9500
- device tree bindings.
Cleanups / Fixes
* ad5755
- fix an off-by-one on devnr limit check (introduced earlier this cycle)
* ad7266
- drop NULL check on devm_regulator_get_optional as it can't return NULL.
* ak8974
- avoid an unused functional warning due to rework in PM core code.
- remove .owner field setting as done by i2c_core.
* ina2xx
- clear out a left over debug field from chip global data.
* hid-sensors
- avoid an unused functional warning due to rework in PM core code.
* maxim-thermocouple
- fix non static symbol warnings.
* ms5611
- fetch and enable regulators unconditionally when they aren't optional.
* sca3000
- whitespace cleanup.
* st_sensors
- fetch and enable regulators unconditionally rather than having them
supported as optional regulators (missunderstanding on my part amongst
others a while back)
- followup to previous patch fixes error checking on the regulators.
- mark symbols static where possible.
- use the 'is it my trigger' help function. This prevents the odd case
of another device triggering from the st-sensors trigger whilst the
st-sensors trigger is itself not using it but rather using say an hrtimer.
* ti-ads1015
- add missing of_node_put.
* vz89x
- rework to all support of new devices.
- prevent reading of a corrupted buffer.
- fixup a return value of 0/1 in a bool returning function.
Staging: vt6655: Remove unused function vnt_key_init_table
The function vnt_key_init_table is not used anywhere in the kernel.

This patch adds the const qualifier to the declaration of the member
name_suffix of structure most_channel_capability. It is needed since it

iio: accel: mxc6255: Fix chip-id check
The initial commit adding support for the mxc6225 assumed the
mxc6225 has a chip-id of 0xe5 based on testing on a single Allwinner
A23 tablet with a mxc6225. Testing on a bunch of other Allwinner
tablets have shown that the chip-id for the mxc6225 is not constant.
A datasheet for the MXC6255 which I've found online says that bits
7 and 6 of the chip-id register are undefined (for the mxc6255), testing
on 5 different tablets with a mxc6225 has found the following ids:
0x25, 0x45, 0x65, 0x85, 0xe5. So it seems that for the mxc6225 bits
7, 6 and 5 of the chip-id register are undefined.
This commit adjusts the chip-id check so that the mxc6255 driver
properly recognizes the mxc6225 in all these tablets.

These functions were only mentioned in the rtw_proc_init_one()
function in drivers/staging/rtl8188eu/os_dep/os_intfs.c, which was
under #if 0 and has now been removed completely.
As they are not used anywhere, and also violate the coding style
rules, remove them.
rtw_proc_init_one() and rtw_proc_remove_one() are two very long
functions that are supposed to create a bunch of proc entries to
access debugging features of the driver.
Should they be moved out of #if 0 thay would not even compile, as they
used functions that have been removed years ago
(create_proc_read_entry()) and they use variables that are not defined
(e.g. rtw_proc_cnt).
rtw_proc_init_one() mentions several other functions that are not
mentioned anywhere else in the kernel tree. Thus, after the present
patch, all of those other functions can be cleanly removed as well, as
they will be not mentioned anymore, not even in disabled code.
Subsequent commits remove those other functions.
Should anybody want to implement (in a proper way) the mentioned
debugging features, they can still fetch this code from the git
history.
staging: rtl8188eu: declare internal function as static
This function is only used inside rtw_recv.c. Which is quite logical,
since it's a timer callback: it is passed as the _fn argument to
setup_timer(). So it is internal to rtw_recv.c and should be static.
These functions have been declared without any implementation since
the first commit (58c434013a22fccfdb14abc2bb8408ca29073b76) and there
has been no mention of them in following commits.
Staging: rtl8192e: mark symbols static where possible
We get a few warnings when building kernel with W=1:
drivers/staging/rtl8192e/rtllib_softmac.c:279:13: warning: no previous declaration for 'softmac_ps_mgmt_xmit' [-Wmissing-declarations]
drivers/staging/rtl8192e/rtllib_softmac.c:773:24: warning: no previous declaration for 'rtllib_authentication_req' [-Wmissing-declarations]
....
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
In addition, some of these functions are declared in different files,
it looks like that we need to clean the codes of this driver up,
but we can repress these warnings first, then clean it up.
so this patch marks these functions with 'static' now.
