staging: zram: remove special handle of uncompressed page
xvmalloc can't handle PAGE_SIZE page so that zram have to
handle it specially but zsmalloc can do it so let's remove
unnecessary special handling code.
Quote from Nitin
"I think page vs handle distinction was added since xvmalloc could not
handle full page allocation. Now that zsmalloc allows full page
allocation, we can just use it for both cases. This would also allow
removing the ZRAM_UNCOMPRESSED flag. The only downside will be slightly
slower code path for full page allocation but this event is anyways
supposed to be rare, so should be fine."
2. change pages_expand with bad_compress so it can count
bad compression(above 75%) ratio.
3. remove zobj_header which is for back-reference for defragmentation
because firstly, it's not used at the moment and zsmalloc can't handle
bigger size than PAGE_SIZE so zram can't do it any more without redesign.

staging: zsmalloc: zsmalloc: use unsigned long instead of void *
We should use unsigned long as handle instead of void * to avoid any
confusion. Without this, users may just treat zs_malloc return value as
a pointer and try to deference it.
This patch passed compile test(zram, zcache and ramster) and zram is
tested on qemu.

be OK as well, both checkpatch and coccicheck only report trivial issues.
staging:iio:dac:ad5791: Move private structs and defines from header to C file
The header for this driver contains some private structs and defines, which do
not have to be shared between multiple source files, as well as the platform
data struct for this driver, which has to be shared with other source files.
Since there is no need to expose those private structs and defines move them to
the source file.

Convert the max517 driver to channel spec. As part of the conversion the
"out_voltage_1&2_raw" property, which updates both channel 1 and 2
simultaneously with the same value, is lost, since this is not really covered by
the IIO spec and has only a limited use case in practice.
Also the channel index for the sysfs files is now zero based instead of one
based, which means all channel numbers will be lower by one. E.g.
"out_voltage_1_scale" instead of "out_voltage_2_scale"

iio: Add helper functions for enum style channel attributes
We often have the case were we do have a enum style channel attribute. These
attributes have in common that they are a list of string values which usually
map in a 1-to-1 fashion to integer values.
This patch implements some common helper code for implementing enum style
channel attributes using extended channel attributes. The helper functions take
care of converting between the string and integer values, as well providing a
function for "_available" attributes which list all available enum items.
This patch add the iio_device_get() function, which increases the reference
count of a iio device. The matching function to decrease the reference count -
iio_device_put() - already exists.
