Now that Comedi has the structures in place to support setting the

staging: comedi: prepare support for per-file read and write subdevices
Comedi devices may have several subdevices that support "read" and/or
"write" asynchronous commands that use the "read" or "write" file
operations for data transfer. The low-level Comedi drivers may nominate
a default "read" subdevice and/or a default "write" subdevice, but it
may have other subdevices that support asynchronous commands.
The Comedi core provides a somewhat clunky mechanism to provide access
to the asynchronous command support of the non-default subdevices. When
a low-level device is "attached" to a core Comedi device, it dynamically
allocates a minor device number for each of the subdevices that support
asynchrounous commands and associates them with files created in SysFS
named "comediX_subdY", where "X" is the minor device number of the main
comedi device, and "Y" is the subdevice number. An application can open
these subdevice-specific files and they behave like the regular
"comediX" files except that the "read" and/or "write" subdevice may be
different to the default chosen by the low-level driver.
This patch adds a layer of indirection between the file object and the
comedi device object to allow the current "read" and/or "write"
subdevice to be altered after opening the Comedi device, on a per-file
object basis. The advantage is that an application only needs to open
the main Comedi device file and can then choose which subdevice it wants
to "read" or "write". The main Comedi device file can be opened more
than once, and each file object can choose the "read" and "write"
subdevices independently.
The new `struct comedi_file` is created on "open" and freed on
"release". It includes pointers to the main Comedi device structure,
and to the current "read" and "write" subdevice structures (which may be
NULL). It also has information to keep track of when a low-level device
has been attached or detached since the previous time the file object
was used. In that case, the current "read" and "write" subdevices in
the `struct comedi_file` will be changed to the new defaults (or set to
NULL). (The change to new defaults is done by `comedi_file_reset()`.
The checking for attach/detach is done by `comedi_file_check()` which
will call `comedi_file_reset()` if there have been any attach/detach
operations since the previous call.)
A subsequent patch will add the ioctls to change the current "read" and
"write" subdevices.

Most comedi subdevices that support asynchronous commands only support
data transfer in either the "read" or "write" direction, as indicated by
the `SDF_CMD_READ` and `SDF_CMD_WRITE` subdevice flags, although a few
support both directions on the same subdevice (though not
simultaneously). The `struct comedi_cmd` structure passed via ioctl
call to set up the command contains a `CMDF_WRITE` flag that can be used
to choose the direction if the subdevice supports both directions, but
the flag is optional if the subdevice only supports data transfer in one
direction.
If the subdevice only supports asynchronous data transfer in a sing
direction, set the `CMDF_WRITE` flag to the correct state so that Comedi
can make use of it later. In the case of the `COMEDI_CMDTEST` ioctl,
the updated flag will be written back to the `struct comedi_cmd` in
user-space. In the case of the `COMEDI_CMD` ioctl, the flag only gets
written back if an error is detected while testing the command, or if
the `CMDF_BOGUS` command flag is set. Since `__comedi_get_user_cmd()`
is called for both ioctls, that's a good place to set the flag.

This function currently fails if the number of samples to add would
overflow the async buffer. Modify it to add the samples that fit so
at least some of the sample data is returned to the user.

staging: android: logger: Add a TODO
A comment about a pre-existing bug data structure definition is added.
This bug was evidently introduced by Xiong Zhou in the patch
bd471258f2e09 ("staging: android: logger: use kuid_t instead of uid_t")
where the code was changed to hide a valid build warning instead of
solving the bug that was identified by it.
