staging: flexfb: Remove initialization to 0

(the initial post had a typo in the short summary, reposting)

This fixes some of the code style issues in the flexfb driver by removing
unnecessary initializations of static variables to 0 or to NULL.

staging: comedi: comedi_compat32.c: absorb raw_ioctl()

`comedi_compat_ioctl()` just calls static inline function `raw_ioctl()`
with the same parameters (although the former returns a `long` and the
latter returns an `int`).  Since `raw_ioctl()` is not called from
anywhere else, just absorb its body into `comedi_compat_ioctl()`.

staging: comedi: comedi_compat32.c: fix COMEDI_CMD copy back

`do_cmd_ioctl()` in "comedi_fops.c" handles the `COMEDI_CMD` ioctl.
This returns `-EAGAIN` if it has copied a modified `struct comedi_cmd`
back to user-space.  (This occurs when the low-level Comedi driver's
`do_cmdtest()` handler returns non-zero to indicate a problem with the
contents of the `struct comedi_cmd`, or when the `struct comedi_cmd` has
the `CMDF_BOGUS` flag set.)

`compat_cmd()` in "comedi_compat32.c" handles the 32-bit compatible
version of the `COMEDI_CMD` ioctl.  Currently, it never copies a 32-bit
compatible version of `struct comedi_cmd` back to user-space, which is
at odds with the way the regular `COMEDI_CMD` ioctl is handled.  To fix
it, change `compat_cmd()` to copy a 32-bit compatible version of the
`struct comedi_cmd` back to user-space when the main ioctl handler
returns `-EAGAIN`.

staging: Remove the Android alarm-dev driver

The functionality provided by the Android alarm-dev driver
should now be present in the timerfd interface (thanks to
Greg Hackmann and Todd Poynor).

As of Lollipop, AOSP can make use of the timerfd if
alarm-dev is not present (though a fixup for setting the
rtc time if rtc0 isn't the backing for _ALARM clockids has
been applied post-Lollipop).

Thus, we should be able to remove alarm-dev from staging.

I removed a couple calls to:

staging: lustre: fix min() comparison types lacks cast build warning

Recent changes to use the builtin min functions [1] introduced
type checking which wasn't present before.  This resulted in
"comparision of distinct pointer types lacks a cast" build
warnings on non X86 architectures [2,3].

  [1]: https://lkml.org/lkml/2014/12/25/145
  [2]: https://lists.01.org/pipermail/kbuild-all/2015-January/008588.html
  [3]: https://lists.01.org/pipermail/kbuild-all/2015-January/008589.html

The call to min() which resulted in this warning took the result
of kiblnd_rd_frag_size(), which returned a __u32, and the
variable 'resid', which is an int.  'resid' is inside a while
loop which is only entered if it is positive.  Casting it as a
__u32 can be perormed without a loss of data or change in
functionality.

Fix the warning by casting 'resid' as a __u32.
